Code for the Textile Game Controller Jam by Social Body Lab, Dames Making Game, & Game Play Lab.
May 30, 2020 - June 6, 2020.
This is code follows along the "How to Make an Capacitive Sensor Using E-Textile Materials" here: https://youtu.be/kTfoMyjtgws
The code contains 1 capacitive sensor which lights up when touched.
