Touch
We’ve played with lights and sound, now let’s play with touch!
Touching different pins on the Express board will trigger different lights and sounds.
Also try playing with the slide switch to enable and disable it entirely.
The touchpad is assigned by its number on the circuit playground.

if cpx.switch:
print("Slide switch off!")
cpx.pixels.fill((0, 0, 0))
