Programming ESP32: Learn MicroPython Coding and Electronics

This book offers a hands-on introduction to Python programming and basic electronics, making no assumptions about your prior experience. It begins with the fundamentals of Python, gradually guiding you through to more advanced concepts using a practical Morse Code project as your starting point.

Focusing primarily on the popular ESP32 Lite and ESP32 DevKit 1 boards, the book includes clear breadboard layouts and detailed instructions tailored for both. You’ll learn how to flash Python firmware onto your ESP32, set up and use the Thonny Python editor, and upload your programs with ease.

As you progress, you’ll develop the skills to write structured Python code using functions and modules, work with powerful features like lists and dictionaries, and interface with sensors, LEDs, displays, and servomotors. Finally, you’ll unlock the ESP32’s Wi-Fi capabilities, learning how to turn your board into a web server or connect it to online web services. More information…
