Запропоновано алгоритм для керування стабілізацією положення двохосевої платформи з використанням біполярних крокових моторів, акселерометра та керуючого мікро- контролера.

In this paper, the authors have proposed the algorithm to control the stabilization position 2-axial platform using bipolar stepper motors, accelerometer and microcontroller.

Mobile devices for information, control and telemetry systems are powered by mobile generators through AC to DC converters, by batteries or, if possible, directly by solar panels. Solar panels typically work in a system that involves the usage of batteries to keep the systems running when the solar panels are not working or not providing enough power. The batteries can be recharged from the panels themselves if the solar panels have sufficient power or from an external direct current source.

We created a system, debugged it, and conducted experimental studies of the two-dimensional rotation of the supporting platform (with a camera, and a light source.) on the source of sound waves. The system was assembled based on two SYNCO Mic-M3 cardioid condenser microphones and an Alesis IO-4 sound card. We wrote original software for analyzing and transmitting the result of processing harmonic acoustic signals for the response of the Arduino Uno control board. The rotation of the 2D platform is caused by two MG995 servos controlled by this microcontroller.

In many cases, visual and optical methods can be used in defectoscopy for different materials and products. With the development of microprocessor components and significant expansion of usage of computer technologies and image processing and analysis techniques in different areas, the use of visual and optical methods in defectoscopy for production and research purposes is rapidly developing.

The goal of the publication is to test the random codes generator of the built-in crypto-protection system

Nowadays, the development of electronics and related technologies is very fast. An extremely significant role in the life of moder society is took by information output devices, the development and modernization of which is an urgent task. Using the idea regarding wireless control of remote devices, an information board with remote control was developed. This article provides a reader with the development of universal information board which customers will be able to assemble for the dimensions that they need.

With the development of microprocessor components and, accordingly, a significant expansion of the use of computer technologies, remote measurement techniques are being developed. These include telemetry and remote control of technical systems or their components in industry, research, home appliances and other fields. In this paper, the author suggests how to build a local web-server based on a microcontroller with an ARM Cortex-M4 core, which can be interacted with via an http-browser with Internet access.

An alert system has been studied, in which sensor data can be collected and analyzed for further processing and action. Notifications are generated when data is compared against certain criteria. The ESP8266 microcontroller has been chosen as the basic device for implementing such a system, as this Espressif controller is a highly integrated Wi-Fi SoC solution that meets the demands of the cyberphysical systems industry in low power consumption, compactness and reliability. This solution is one of the most effective for the alert system.
