Audio Activated Switch. This device allows audio to activate an electronic switch. The circuit is essentially a one channel color organ (for those that remember what those are), but with a small twist. This unit has three channels that turn on whenever the preset volume level or greater is achieved. The volume level can be adjusted by you.

Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave which is further amplified by op-amp. 555 timer IC acts as mono-stable multi-vibrator then flip-flop changes the state of output relay on …
