Prototyping and Engineering Tips from Robogears
Wiring Guide: Always follow the provided instructions: Connect the Red & Black wires to the LED and the White & Orange wires to the Mic. Reversing these will prevent the circuit from triggering.
Sensitivity Check: For the best response, clap your hands roughly 12–24 inches away from the microphone. If it doesn't trigger, ensure the mic "head" is pointed toward the sound source and not covered by tape.
Environmental Noise: In a very noisy classroom, the switch may stay "on" constantly. Try to demonstrate this in a quiet area so the mic can distinguish the "clap" sound from background chatter.
Battery Life: If the LED appears dim or the switch fails to turn off, it usually indicates the 9V battery is low. Replace with a fresh battery to restore the 15-second timing accuracy.
