The ESP32 is a powerful and affordable microcontroller, ideal for both simple and advanced applications thanks to its rich feature set. MicroPython, based on Python 3, is an excellent and easy-to-use language for programming the ESP32. Despite being slower than C, it’s often fast enough and far more accessible for beginners. After a quick setup, you can start coding using Thonny or PyCharm. This book guides you through using the ESP32’s GPIO pins with sensors, servos, motors, and ADCs.
