This book will help you quickly master the basics of robotics and start designing your own robots, various systems with microcontrollers and even smart home elements. You do not need knowledge of programming languages ​ ​ and a soldering iron. Learn microcontrollers and robotics from our book, and you can quickly master modern professions. You will learn how to program micro: bit versions 1.5 and 2, work with buttons, LEDs, LED and OLED screens, measure temperature, acceleration, magnetic field strength. Using the GPIO interface, you connect devices such as motors, servos, buttons, motion sensors, distances and many others. The data received from the controllers can be transmitted to other controllers using the Bluetooth radio channel, as well as LoRa controllers capable of providing radio communication over distances of kilometers. We will tell you how to organize the power supply of a robot or other structures.
