Clap Switch Using 555 Timer. Remote access to electrical devices are makes us comfortable and if you can control electric device with clap then it makes you very joyful and here we have prototype a simple clap on clap off switch using 555 timer and this circuit can help us to control any electric device here for an example we have taken electric bulb. It converts sound energy into electrical energy which then raises the potential at the base pin and turns on the transistor.

It consists of condenser mic to pick sound of the clap and convert from sound energy to electrical energy which is then used to trigger 555 timer output where led is connected.
Clap switch is an interesting hobby circuit which turns on the lights with a clap sound.
The mic 1 condenser microphone is used here as sensor senses the clap sound and further convert it into electrical signal. Here we are using electric condenser mic for sensing the sound transistor to trigger the 555 timer. This is a simple electronic project and mostly used to turn on and off ac appliances with the help of sound.
