WebJul 2, 2024 · The loop () code looks for a set flag, and if it finds one, generates a 50uSec pulse on a selected pin, delays 100mSec, resets the flag, and exits. As long as the switch's contact bounce activity ceases before the 100mSec delay expires, one and only one pulse per transition will be generated. YMMV.
