Touch sensor on T0

Checks

Run your code to check it. The checks replay a fixed script on a virtual clock, so the same code always gets the same result.

1. Touching the wire lights the LED · Not checked yet
2. Letting go turns it off · Not checked yet
3. The readings stream to the serial monitor · Not checked yet

Break it

Each fault really happens in the simulation. Trigger one, watch the figure, then read why.
