Our lessons will be especially useful for both beginner radio amateurs and students of radio engineering universities, as well as for experienced electronics engineers who solder every day! In the videos, we give the basics of electronics: definitions, descriptions, diagrams and the operating principle of various elements of radio engineering. The channel provides lessons on Arduino / Arduino; we analyze programming, connection of sensors, modules, displays, motors; we create various projects and devices on Arduino.
