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 with 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 can connect devices such as motors, servos, buttons, motion sensors, distances, and more. You can transfer the data received from the controllers to other controllers using the Bluetooth radio channel, as well as LoRa controllers that can provide radio communication over distances calculated in kilometers. We will talk about how to organize the power supply of a robot or other structures.
