MicroPython and IoT Projects: Program Microcontrollers and Gadgets with Python

Build smart devices. Learn MicroPython. Bring your ideas to life.

MicroPython and IoT Projects is your beginner-friendly guide to using Python on microcontrollers like the ESP32 and Raspberry Pi Pico. If you've ever wanted to control lights, sensors, or other hardware with Python instead of C or Arduino, this book is for you.

Designed with practical learners in mind, this book walks you through step-by-step projects that combine coding with real-world hardware. You'll connect sensors, push data to the cloud, and even control devices from your phone-all while writing clean Python code that runs on tiny, efficient boards.

Inside, you'll build projects like:

• Wi-Fi Temperature Logger - Monitor room temperature and push data to a Google Sheet or web dashboard

• Motion-Activated LED Alarm - Detect movement and trigger lights or buzzers

• Bluetooth Device Controller - Control gadgets wirelessly with your phone

• Smart Plant Monitor - Measure soil moisture and send alerts when to water

• IoT Button - Send custom commands to web apps or smart home platforms

• OLED Screen Data Display - Show sensor values or messages on a small screen

You'll learn how to:

• Flash MicroPython firmware onto ESP32 and Raspberry Pi Pico

• Connect sensors and actuators using GPIO

• Work with Wi-Fi and Bluetooth

• Send and receive data over MQTT, HTTP, and APIs

• Use libraries like umqtt, urequests, and machine

• Troubleshoot, optimize, and expand your projects

Whether you're an electronics hobbyist, Python coder, or tech educator, this hands-on book gives you everything you need to start building real IoT projects with Python, not theory.
