The manual is devoted to the study of the basic principles of modeling and building electronic circuits, programming microcontrollers and robots. The first part of the manual discusses the development of our own electronic circuits, uses a wide range of components: from transistors and LEDs to servomotors and Arduino boards, which allow you to program intelligent control of circuit elements. The second part is devoted to more complex issues, namely programming the logic of the behavior of robots: moving in space, avoiding obstacles, interacting with the environment.
