• README.md - Documentation and usage instructions

🚀 Getting Started

1. Install Arduino IDE - Download from arduino.cc
2. Install ESP32/ESP8266 Board Support - Follow the setup guide in Workshop 01
3. Open an Example - Navigate to any workshop folder, open the example folder, and double-click the .ino file
4. Follow the Workshop - Visit the corresponding workshop page on cardanothings.io for detailed instructions

📖 Using the Examples

Each example is designed to work with the Arduino IDE. Simply:

1. Open the .ino file in Arduino IDE
2. Install any required libraries (instructions in each example's README)
3. Update WiFi credentials and other configuration as needed
4. Upload to your microcontroller
