Currently designed for the Raspberry Pi Pico running MicroPython. This will change as I need radio communications.
This is very much experimental, and is based upon custom wiring. Your mileage might vary.
Following the Pico schematics, in this setup the following is assumed:
Pin 27 - GP21 | Tube button, connected to GND on pin 18.
Pin 29 - GP22 | Tube LED Mosfet gate (pass 9V battery supply).
For the most part this project follows this instructables guide.
