Abstract
"This article discusses a technological solution developed on the basis of an Arduino-type microcontroller with automatic control of air heating in production. Currently, microcontrollers have a large range (more than 10,000), which differ among themselves in terms of application, parameters and other properties. Dozens of manufacturers are engaged in the release of microcontrollers. Increasing reliability, speed and functional saturation, as well as reducing the amount of modern computer technology and electricity consumed have led to its widespread use to control complex technological objects with a large number of physical quantities and controlled installations. The result of this article will be the development of a block diagram, drawing up a schematic diagram of a control system, block diagrams, writing a program for a microcontroller, developing an operation algorithm and a set of elements that can be used in any production, production process (for example, drying systems, heating installations, etc.), where an air heating control system is deemed necessary. Also, the main conclusions, concepts of this research work can be used in production processes, household appliances and as a teaching aid. "
