ESP32 & MicroPython Playground

📖 About This Repository

Welcome to my personal playground for embedded systems! This repository serves as a living document of my learning journey with the ESP32 microcontroller and MicroPython. Here, you'll find a collection of hands-on projects, each designed to explore a specific piece of hardware, a programming concept, or a real-world application.

The goal is to move from fundamental concepts like hardware drivers to more complex integrations involving sensors and connectivity. Each project is self-contained and includes the necessary code and wiring instructions to be reproduced.

🌱 Future Goals

This repository is an ongoing project. I plan to explore more advanced topics in the future, such as:

• Wi-Fi and Bluetooth connectivity
• Communicating with web services and APIs
• Using protocols like MQTT for IoT
• Interfacing with I2C sensors (e.g., temperature, humidity)
• Exploring sleep modes for battery-powered projects
