This beginner-friendly book teaches Python programming and basic electronics with no prior experience required. It starts with a Morse code example to introduce Python and focuses on ESP32 Lite and DevKit 1 boards. You'll learn how to flash firmware, use the Thonny editor, write Python programs, and connect components like LEDs, sensors, and servos. The book also shows how to use the ESP32’s Wi-Fi for building web servers and accessing online services.

In this hands-on project, you’ll learn how to control devices remotely using an ESP32 board, a relay, MicroPython, and tunneling software. We’ll guide you through setting up the hardware with a breadboard and relay module, installing the Thonny IDE, flashing MicroPython firmware, and running a web server on the ESP32 to control devices via your local network. You’ll also set up ngrok for secure remote access from anywhere. By the end, you’ll have a fully functional web-controlled relay switch, with code available for download.

Step into the world of Internet of Things innovation, where each chapter distills complex concepts into clear, practical lessons—complete with full Python code examples. Whether you're a budding developer or a seasoned coder, you'll appreciate the engaging, step-by-step approach that transforms theory into real-world applications. Learn everything from digital I/O and sensor integration to wireless connectivity and secure communications.

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.

Explore the ESP32's capabilities through hands-on tutorials, covering everything from basic programming and sensor integration to advanced topics like Wi-Fi, Bluetooth, and machine learning.
