Clap switch/voice activated switch designed around Microcontroller. This project is free from false triggering. To turn
on/off any appliance, you just have to clap twice. The sound of
clap received by microphone, microphone changes the sound
wave in to electrical wave which is further amplify by transistor.
The Micro-controller act as mono stable multi-vibrator which
changes the state of output relay on every two claps.
