Interdisciplinary communication of physics, schemes and programming

Abstract

The article presents the results of the development of an electronic device based on digital components, carried out jointly with schoolchildren and students. 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.
