Logic boards were failing at Enhanced Mac Minus One (EMMO) test or Integrated Circuit Test (ICT) after printed circuit board (PCB) rework. The failure to boot was originally traced to a suspected bad microcontroller chip. Replacing this chip, or an oscillator tied to the microcontroller circuit, did not consistently solve the boot problem. With further testing, it was found the microcontroller circuit was very sensitive to resistance and was essentially shorted.A resistor in the microcontroller circuit was identified on the flip side of the PCB. Several areas on the board, including the resistor R161, were seen to have a slight white haze/ low gloss appearance on the surface of the PCB. To test if the residue was electrically conductive, five boards were selected whose sole failure was R161. The resistance of the individual resistors was measured with a digital multimeter (DMM). The resistor was then cleaned with isopropyl alcohol and a cotton swab. Each board was retested at ICT and the individual resistors measured again with a DMM. Cleaning the area surrounding the resistor with isopropyl alcohol, corrected the failure four of the times.

In this paper, a new hybrid test strategy, called hybrid-based self-test (HYBST), is presented to test complex digital circuits such as microcontrollers. This test strategy integrates the signature multi-mode hardware-based self-test (SM-BST) with the software-based self-test (SBST). In this test strategy, the microcontroller is divided into a number of main modules, and then test subroutines are used to functionally test each module, based on its instruction set architecture (ISA). The ISA is used to generate test subroutines that represent test pattern generators (TPGs) and part of the test controller. The SMHBST represents the other part of the test controller and the test response compaction (TRC). The experimental results illustrate the superiority of the HYBST in the memory utilization, test application time, testing of internal modules of the microcontroller, and testing of general-purpose input-output (GPIO) pins of the microcontroller. In addition, an integrated test solution for fault diagnosis of the circuit boards including random logic integrated circuits (ICs) and microcontroller chips is presented to indicate a real practical test strategy.

The article highlights the results of developing an electronic module for testing Arduino boards. The hardware and software platform mentioned is often used for educational purposes to study microcontroller systems and robotic devices. The ability of testing the board before reusing it helps troubleshoot the electronic device. In the course of the study electrical structural and circuit diagrams of the module were developed, and a special test program was created. The module implements software and hardware diagnostic methods, which allows testing with high precision and ensuring the necessary reliability of robotic devices developed on its basis. To create a diagnostic module there were identified the nodes of the Arduino hardware-software platform with a high failure rate, an input-output line check node, an ADC and power system check node, an EEPROM check node and a power supply with a fuse. A practical value of the development lies in the fact that the test program is loaded directly into the microcontroller of the tested board allowing to quickly and accurately test I / O lines with a high failure rate. Nowadays, there are no such devices for diagnosing malfunctions of the Arduino hardware and software platforms. Using the Arduino software and hardware platform in educational processes opens the new opportunities for both students and schoolchildren. Projects implemented in secondary professional technical institutions motivate students to acquire new knowledge, develop interest in technology, programming and design, develop logical and algorithmic thinking.

Full textAbstract:
Recently, a wide range of small devices, such as Wi-Fi Internet of things development boards, which are a kind of the microcontroller units in a general purpose board, are interrelated throughout the planet. In addition, certain microcontroller units interact inside our homes when turning lights on or detecting movements, measuring various parameters, such as gas concentrations, [Formula: see text], humidity, and the temperature inside a room, or adjusting the intensity of the lights inside and outside of the house. Likewise, there is a great diversity of microcontroller units, ranging from smart cellular telephones or reduced general purpose devices, ESP8266 or RaspberryPi3 to any type of Internet of things devices. Therefore, the general way of connecting the microcontroller units to the Internet is through hub nodes, so that the information can be propagated and shared among them. The main purpose of this article is to yield an adaptive reconfiguration algorithm to link all the sensor nodes (microcontroller units) of a network based on the fractal topology, avoiding the use of hub nodes, in order for the microcontroller units to share all the parameters established in the Internet of things network only through two adjacent sensor nodes as long as any sensor node in the network knows all the parameters of the other ones, even if the sensor nodes are not adjacent. To achieve the above, in this work, an Internet of things network was built based on the Hilbert fractal for being a filling-space curve yielded from the L-systems paradigm, so this fractal Hilbert topology allows access to the entire Internet of things network in a dynamic way, and it is possible to reconfigure the network topology when a new sensor node is attached by applying artificial intelligence to intelligent and dynamic environments.

Currently, the department of Jabatan Kerja Raya (JKR) in Malaysia depends on the notification from public’s complaints or on-site spot checks when there are tilted road sign boards. This has caused delays in repairs and could put public safety in jeaopardy. In this paper, an IoT-based alert notification for tilted road sign boards using solar energy is proposed. A Rapid Application Development methodology (RAD) is used to produce a working prototype of the proposed system with NodeMCU ESP8266 microcontroller and Arduino IDE.

Arduino microcontroller platforms are frequently in use in the last few years. The reason is their simplicity, low cost, and availability of a large number of ready-made solutions on the Internet. The Arduino Integrated Development Environment itself has a Serial Monitor and Serial Plotter tools for data presentation. The Serial Monitor displays the textual and numeric values of the data obtained through the serial port. By using the Serial Plotter, measurement results from the Arduino serial port can be seen in the form of Real-Time diagrams. The deficiency of such a way of data visualization is that it does not provide many opportunities for change and adaptation to the user needs. This paper presents examples of several different programming environments which provide the good opportunities for presentation the results generated by the Arduino boards. Some hardware modules used to display data from the Arduino boards are also described in this paper.

The aim of this work was the design and development of an electronic device based on 32-bit microcontrollers of the STM32 series. For the design and development of the electronic part of the device, the integrated development environment Altium Designer was used. Using a high-level C ++ language, a control program was developed in the Keil v.5 debugging environment. The microcontroller of the STM32F030K6T6 series was used as the central control processor. The electrical circuit and the circuit board of the device are developed. A highly sensitive gas sensor TGS 2610, manufactured by Figaro (Japan), was used as a sensor element. For SMS transmission, the SIM800A module was used. In the process of doing the work, students independently made electric boards using the method of irradiation of a special photoresist with a UV lamp. Practically all the components were arranged and soldered by the students on their own. Together with the students, a control program for the microcontroller was developed. To manufacture the case of the device, the «KOMPAS» environment was used. The case was printed on a 3D — printer. Calibrated the device and its test tests. According to the results of preliminary test tests of the device, it was found that the gas sensor responds to the presence of gas during the first 20 seconds from the time the leak started. False positives of the device are not fixed. The importance of the foundations of physics, computer science and mathematics in the process of designing digital devices and instruments is shown.

Sensor networks that collect data from the environment can be utilized in the development of context-aware applications, bringing into sight the need for data collection, management, and distribution. Boards with microcontrollers, such as Arduino and Raspberry Pi, have gained wide acceptance and are used mainly for educational and research purposes. Utilizing the information available via sensors connected to these platforms requires extended technical knowledge. In this work, we present a sensor management framework, SensoMan, that manages a collection of sensors spread in the environment connected to microcontroller boards. We present the framework’s architecture, a method for sensor data management, and a prototype system. Sensor data can also trigger the execution of actions on actuators. Thus, we further propose a rule engine as well as social connectivity following a scheme where sensors and their data can be shared among users. Our work shows that the creation of such a system is feasible and can use simple equipment (e.g., sensors, controller plugs) that can be replicated in other environments. The use of SensoMan is demonstrated via two scenarios that show its potential in combining simple tools that do not require an extended learning curve. A small-scale user study was also performed.

This research paper presents an alternative way to fabricate a Milled Circuit Board (MCB) with the help of a Computer Numerical Controlled (CNC) milling robot. Printed Circuit Boards (PCB) are one of the most widely used control modules in electrical and electronic industries. In this research paper we propose a computer controlled milling machine which can be used for quick fabrication of double layered PCBs called MCB where a user wants to test the circuit without the need to wait for the conventional PCB fabrication. The end effector of the CNC milling machine has the provision to move in 3 axes-x, y and z in accordance with the input received from the controller. DipTrace, an EDA/CAD software is used for creating the schematic diagram for the milled circuit boards. The design to be engraved on the copper clad board is uploaded to a software called CopperCam, where it can be converted to G-code files after making the necessary modifications. These G-code files are then uploaded to the CNC machine using the software Universal G-code Sender, thus enabling the microcontroller to direct the rotation of motors and coordinate the movements of the end effector so as to engrave the board design on to a copper clad.

Maximum power point trackers have a significant role in optimizing the energy conversion efficiency in a photovoltaic system. The numeric achievements of MPPT algorithm can be implemented and tested by using several embedded boards as Digital Signal Processor, Field-Programmable Gate Array, Arduino, and dspace. Alternatively, for the low cost, availability and simplicity, the PIC microcontrollers can be used compared with the other hardware devices. Therefore, this paper presents the implementation of a Takagi–Sugeno fuzzy controller on a low cost PIC microcontroller, for tracking the maximum power point of a PV module. The PV system consists of a PV emulator, DC-DC converter, and resistive load. The different steps in design, simulation and realization of the T-S Fuzzy logic controller are discussed. The proposed controller system was evaluated by comparing its performance metrics, in terms of efficiency and the Integral Square Error, with existing technique in the literature. The results corresponding to the experimental validation show that the proposed MPPT controller is able to ensure a perfect tracking of the maximum power point with variation of irradiance and is performing better than reported in a previous work.

After multiple testing, the model is found to have 95 percent accuracy. Model used is Sequential and uses Convolution Neural Network (CNN) as its architecture. The activation function of each layer is RELU and for the output layer is Softmax. The output is a prediction and hence it is of probability type. This is a type of an application based project.

<p>Currently, there are many small business outlets that have opened branches in many places. With the spread of outlets that are far apart, it becomes a problem for the owner to be in a certain place on a display board that is installed at a height in each of his outlets. Display boards that are commonly used as promotional media and usually show product prices/interesting information are running text boards. In some studies there are those who make ESP as an access point, so that it can only be accessed within the range of the access point. So it cannot be accessed remotely. To facilitate this information, in this study, we designed an internet-based mobile text information system using the ESP32 Microcontroller and the Message Queuing Telemetry Transport (MQTT) protocol, as well as a display board (DMD LED Panel P10). By using an android-based mobile device that is owned by almost everyone and then equipped with the MQTT application, it is hoped that information will no longer be constrained by distance and the absence of a computer device, as well as the limited number of computer operators.</p><p> </p><p class="IndexL-MAG"> </p>

The advantages and disadvantages of Arduino controllers in relation to refrigeration automation systems are considered. An example of using the Arduino controller for creating an automation and monitoring system for a non-standard laboratory refrigeration unit is presented. Arduino is a computing hardware platform for affordable design, the main components of which are the microcontroller board with input and output elements, as well as the Processing / Wiring programming environment in a programming language similar to C, C ++. Arduino can be used to create standalone interactive objects, connect to the software that is used on your computer. The main advantage of using Arduino-based controllers is the availability of information about the microcontroller card, the specification of the elements, the software. Information is freely accessible and can be used by developers in any field. Microcontroller boards have a special structure, due to which, if necessary, it can be expanded by adding new components to the device. Thus, the presented platform allows to improve or change the operation of the automation system of the refrigeration unit, depending on the requirements of the consumer of the cold. The presented variant of automation of refrigeration systems gives an opportunity to come up with a new approach to the design of refrigeration units. During the development of the automation system, a modular algorithm for controlling and protecting the refrigeration unit was created in all its variants, the necessary peripheral equipment and signal receivers were selected. It is shown that the value ratio - functionality of these devices significantly exceeds the similar indicators of the world's leading manufacturers of refrigeration automation systems.

AbstractThe design of a novel MEMS (Micro-Electro-Mechanical System) sensor-based monitoring system is presented in this article for the in situ monitoring of the conditions (temperature, relative humidity) of an engineered bentonite barrier for the underground disposal of radioactive waste in a geological disposal facility (GDF). A first prototype of the monitoring system incorporating multiple state-of-the-art MEMS sensors has been developed on a PCB-based (Printed Circuit Board) structure, in order to measure the variation of temperature and relative humidity inside a cylindrical bentonite block during the hydration process. The monitoring system comprises separate sensor boards, the microcontroller-equipped interface board and the software user interface in the Labview environment. One of the main design priorities is to reduce the size of the embedded sensors in order to minimize their influence on the hydro-mechanical response of the bentonite block. The sensor boards are encapsulated in different manners to protect them from moisture, chemical corrosion and mechanical shocks. The sensor system has been tested and calibrated in the temperature range between –20°C and 120°C, and at different relative humidity levels implemented by saturated salt solutions in enclosed containers. Test results demonstrate that the sensors have shown good functionality and robustness in harsh test environments such as high temperature and high humidity. Both temperature and relative humidity sensors have shown satisfactory precision level and temporal stability, which are in good accordance with the design specification of these devices.

Battery Monitoring System (BMoS) is an electronic system that monitors rechargeable battery cells or packs with various parameters, such as battery voltage, current and State-of-Charge (SoC). This system can be used to avoid overcharging or over-discharging of batteries to increase its shelf life. However, BMoS on the market is very expensive and not suitable for low cost embedded systems. As the Arduino Uno is widely used for low cost microcontroller boards, easy programming environment, and open-source platforms for building electronic projects, therefore, this study focuses on Arduino Uno BMoS based system. This system consists of current and voltage sensors, an Arduino Uno microcontroller and a liquid crystal display (LCD). In order to develop this system, there are three objectives to be achieved. First, the relationship between input and output of the sensors must be derived mathematically. The mathematical expression obtained can be verified by connecting and disconnecting the circuit with load and monitoring the value of output sensors. Then, a complete prototype of the BMoS was developed by connecting the LCD, current and voltage sensors to the Arduino Uno microcontroller. The complete prototype was tested using an 11.1 V of Lithium-ion battery and a DC motor as a load. From the results, the current sensor shows zero value when no load is connected as no current flow. The LCD also displays 11.1V of battery voltage when fully charged. Using the developed system, the user can monitor the current, the voltage and the SoC of the battery to ensure the battery is not overcharged and overused. The development of the BMoS can help to monitor the operation and performance of the batteries in any electronic systems. At the end of this study, the complete BMoS prototype gives benefits to the user and makes work easier.

Very recently, implementations of these devices for diagnostics applications are rapidly gaining ground for research and educational purposes. Among the available solutions, Raspberry Pi represents one of the most used SBCs. In the present work, two setups based on Raspberry Pi and its CMOS-based camera (a 3D-printed device and an adaptation of a commercial product named We-Lab) were investigated as diagnostic instruments. Different camera elaboration processes were investigated, showing how direct access to the 10-bit raw data acquired from the sensor before downstream imaging processes could be beneficial for photometric applications. The developed solution was successfully applied to the evaluation of the oxidative stress using two commercial kits (d-ROM Fast; PAT). We suggest the analysis of raw data applied to SBC and MCB platforms in order to improve results.

Arduino UNO R3 is one of the cheapest and easiest microcontroller boards that has great potential to be used as a basis for the measurement system. This study aims to develop measurement system of crude oil capacitance by using IDCs(Interdigital Capacitors). By knowing the value of crude oil capacitance, the crude oil permittivity value can be calculated. The crude oil permittivity value data is extremely needed in making crude oil heating systems using microwaves. The study used IDC sprinted on a PCB board with a copper layer as the electrode. Then, the system measurement results were compared with the results of PM 6303 RCL meter Phillip type A frequency measurement of 1 kHz which was used as reference data to determine the extent of measurement errors. From the results obtained, it is known that the error value of the Arduino UNO R3 based capacitance repeatability measurement is 0.47%. While the results of the linearity test measurement of crude oil capacitance measurement of temperature increases using the Arduino Uno-based IDCs sensor, the R2 value is 0.87. Thus it can be seen that the Arduino UNO R3-based capacitance measuring device has quite good sensor characteristics.

The ability of Arduino boards to be connected with electronic devices or gadgets such as Android operating system devices is getting more attention among researchers. By utilizing the various capabilities possessed by most Android operating system devices on the market today, the Arduino board will certainly have extraordinary intelligence. Some of the ways that Android devices can communicate with Arduino are via a Bluetooth shield, Wi-Fi shield, and also by serial communication. The idea that emerged was to utilize the ATMega328 microcontroller serial communication capability on the Arduino board. Serial data sent from an Android device is passed through an audio jack cable then connected to the Rx port on the Arduino board. In this Final Project will be designed and realized serial communication between the Android and Arduino platforms through audio channels with text input with the aim that Android can send text data through audio channels with audio cables. In testing the data speed utilizing the Arduino serial monitor it was found that the optimal speed was 19200bps. Whereas the maximum speed is 38400bps which can still be used for uniform serial data communication with an error of less than 5%. However, the maximum speed cannot be used for diverse data because the data error is more than 30%. The data cannot be read at speeds of 14400bps, 28800bps, speeds under 300bps and speeds above 57600bps.

We describe the design and performance of an electromechanical system for conducting multineuron recording experiments in alert non-human primates. The system is based on a simple design, consisting of a microdrive, control electronics, software, and a unique type of recording chamber. The microdrive consists of an aluminum frame, a set of eight linear actuators driven by computer-controlled miniature stepping motors, and two printed circuit boards (PCBs) that provide connectivity to the electrodes and the control electronics. The control circuitry is structured around an Atmel RISC-based microcontroller, which sends commands to as many as eight motor control cards, each capable of controlling eight motors. The microcontroller is programmed in C and uses serial communication to interface with a host computer. The graphical user interface for sending commands is written in C and runs on a conventional personal computer. The recording chamber is low in profile, mounts within a circular craniotomy, and incorporates a removable internal sleeve. A replaceable Sylastic membrane can be stretched across the bottom opening of the sleeve to provide a watertight seal between the cranial cavity and the external environment. This greatly reduces the susceptibility to infection, nearly eliminates the need for routine cleaning, and permits repeated introduction of electrodes into the brain at the same sites while maintaining the watertight seal. The system is reliable, easy to use, and has several advantages over other commercially available systems with similar capabilities.

Abstract: For people who are intellectually challenged, this document provides a sign to speech translator. In contemporary society, the dumb have very little ability to converse with the normal person. Therefore, they are unable to interact with common people until common people, like ourselves, learn how to communicate through sign language. Dumb sign language is not something that everyone can learn because it is so challenging to perfect. Because of this, nobody can go and talk to these physically challenged persons. So, here is a system that would make it possible for those who are illiterate to speak with everyone. With today's technology, even the deaf may communicate by making hand gestures. Each hand gesture is set to play back a different audio message. Hand motions were captured by a flex sensor and an accelerometer, and the microcontroller then accepted these inputs. The flex sensor tracks hand movements and detects deflections, converting them into the right signals that trigger the system to produce recorded sound signals for transmission via the speakers. There are many different Arduino Boards available right now, and they can be used for a variety of things. The Arduino Mega 2560 is the ideal solution since it is the most cost-effective, allows faster computing, and can integrate and interface various sensors while consuming less power. The device under discussion is basically made up of a glove and a microcontroller-based system. Four strategically placed flex sensors are included in the data glove.

As a result, the operations (actions) that need to be taken are determined: automatic centering, reset, cancel, etc. Using emulation with additional microcontroller connections, the problem of limited installer resources and the implementation of more complex algorithms in the installer's work is solved.

Full textAbstract:
The rising world population is posing threats to global food security. The problem is more serious in urban areas where there is scarcity of farming land and water. Further, global warming is making it more and more difficult to plant crops in an uncontrolled environment. In traditional soil based farming method, farmers require good quality of soil with natural minerals. Soil based farming consumes more resources such as water, fertilizers and space. It also requires higher working cost for tilling and removal of weeds.
Hydroponic farming is a soilless urban market gardening technique that aims at providing fresh farm products, at low costs mainly in urban areas. It has the potential of alleviating food security challenges. However, this practice requires constant monitoring of the farm environment.
Falling prices of advanced microcontroller boards and sensors is making it possible to control and monitor a farm without or with less human intervention.
And wireless sensing makes this even more convenient and less messier.

Full textAbstract:
As the COVID-19 pandemic emerged, everyone’s attention was brought to the topic of the health and safety of the entire human population. It has been proven that wearing a face mask can help limit the spread of the virus. Despite the enormous efforts of people around the world, there still exists a group of people that wear face masks incorrectly. In order to provide the best level of safety for everyone, face masks must be worn correctly, especially indoors, for example, in shops, cinemas and theaters. As security guards can only handle a limited area of the frequently visited objects, intelligent sensors can be used. In order to mount them on the shelves in the shops or near the cinema cash register queues, they need to be capable of battery operation. This restricts the sensor to be as energy-efficient as possible, in order to prolong the battery life of such devices. The cost is also a factor, as cheaper devices will result in higher accessibility. An interesting and quite novel approach that can answer all these challenges is a TinyML system, that can be defined as a combination of two concepts: Machine Learning (ML) and Internet of Things (IoT). The TinyML approach enables the usage of ML algorithms on boards equipped with low-cost, low-power microcontrollers without sacrificing the classifier quality. The main goal of this paper is to propose a battery-operated TinyML system that can be used for verification whether the face mask is worn properly. To this end, we carefully analyze several ML approaches to find the best method for the considered task. After detailed analysis of computation and memory complexity as well as after some preliminary experiments, we propose to apply the K-means algorithm with carefully designed filters and a sliding window technique, since this method provides high accuracy with the required energy-efficiency for the considered classification problem related to verification of using the face mask. The STM32F411 chip is selected as the best microcontroller for the considered task. Next, we perform wide experiments to verify the proposed ML framework implemented in the selected hardware platform. The obtained results show that the developed ML-system offers satisfactory performance in terms of high accuracy and lower power consumption. It should be underlined that the low-power aspect makes it possible to install the proposed system in places without the access to power, as well as reducing the carbon footprint of AI-focused industry which is not negligible. Our proposed TinyML system solution is able to deliver very high-quality metric values with accuracy, True Positive Ratio (TPR), True Negative Ratio (TNR), precision and recall being over 96% for masked face classification while being able to reach up to 145 days of uptime using a typical 18650 battery with capacity of 2500 mAh and nominal voltage of 3.7 V. The results are obtained using a STM32F411 microcontroller with 100 MHz ARM Cortex M4, which proves that execution of complex computer vision tasks is possible on such low-power devices. It should be noted that the STM32F411 microcontroller draws only 33 mW during operation.
