I am the proud owner of a Raspberry Pi Pico which is a dinky microcontroller from the lovely people at Raspberry Pi. I also have the RGB Pico Keypad Base, because my husband was buying something else from Pimoroni (3D printer filament, more on that another day) and we love them and … here we are :)
I’ve tried to write down and link to the stuff I found useful along the way with this project, in case it helps you too. Well, no, really so I can come back to it next time I’m using one of these!
