A collection of hands-on IoT projects built with CircuitPython on the Raspberry Pi Pico 2 W — exploring sensors, displays, wireless communication, and more.
Projects are added gradually. No fixed schedule — just consistent learning. 🚀
- Raspberry Pi Pico 2 W (primary board)
- Various sensors, displays, and modules (listed per project)
- CircuitPython
- Adafruit CircuitPython Bundle
- Mu Editor / Thonny / VS Code
