Raspberry Pi Pico PCB uses all 26 pins in custom capacitive touch sensor
The Raspberry Pi Pico, a microcontroller with an abundance of GPIO pins, provides ample opportunities for creative projects. Tom Fox’s latest project, Spoke, exemplifies this by transforming all 26 pins on the Pico into individual touch sensors using a custom PCB. Fox’s journey began with the realization that a 1M […]
