The main objective of this document was to realize the system a practical model of the system for active monitoring the position of light based on the Arduino platform, and to continuously monitor its work. Multiple photovoltaic panels can be connected to the selected controller, but all tests and measurements have been performed on a single panel. This document describes in detail all the electronic components that were required to create the model. The communication between the computer and the controller of the photovoltaic panel is described. An application has been created that allows the user to manually and automatically control the photovoltaic panel. It also describes the processing of an analog signal that needed to be averaged to allow the controller to control the rotation angle correctly.
