Clapper Circuit

Switches LED on after receiving 3 claps in under 2 seconds, spaced at least 0.5 seconds apart.

The circuit amplifies mic input, filters out low frequencies, consolidates the impulse into a single pulse and the Arduino processes the resulting signal.

0:00 - 0:06 : Successful clap sequence
0:07 - 0:12 : Slow claps fail
0:12 - end : Fast claps fail
