A capacitive touch board for the Raspberry Pi Pico

Tom Fox’s SPOKE board is an easy way to add up to 26 touch sensors to projects for interaction. Anything with capacitive potential can be connected to the pins and used to control computer inputs.

Create your own USB MIDI device, game controller, key mapper or other computer interface device by attaching metallic objects, conductive inks, conductive threads, fruits, plants, vegetables, cutlery, car keys, mushrooms etc. or use it just as a standalone device.

The custom circuit board houses a Raspberry Pi Pico. USB MIDI and keyboard are accommodated via CircuitPython code (GitHub).

Using Adafruit’s CircuitPython meant coding was super simple. So far I’ve been using it for USB-MIDI interfacing and also as a HID device to emulate keyboards and mice. mouses. Because of the simplicity of CircuitPython + Pico, the code can be edited in Notepad without needing to download any IDE’s.

See the video below for the SPOKE in use and details on the project website and hackster.io.
