Using an electric shock to trigger an arduino. (doorknob variety) Answered
I was thinking a transistor, how does one make ~20000v at 5mA useful. Do I use a capacitor or a coil of some type? Do I NEED an amp? Will it be jittery? I was even looking at those alfoil leaf static detectors and imagining some sort of field detecting reed switch.. ?
