I have to admit I am a bit confused about this issue right now.
After BigRig's advice I tried this out with a few different switches
and the circuit outputs a trigger upon closing AND opening of the
switch, whenther its a toggle switch or a momentar button OR a piezo
switch. Any way to prevent this double triggering?
