Модуль для проверки плат семейства Arduino

Abstract

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.
