Clap Switch Circuit Block Diagram. Clap switch circuit using 555 and 4017. The main component of this clap switch circuit is the electric condenser mic which has been used as a sound sensor.
You can see the circuits and connections in the above schematic diagram of clap switch. Initially the transistor is in off state because there is not enough 0 7v base emitter voltage to turn it on. And the point a is at high potential and point a is connected to trigger pin 2 of 555 ic as a result trigger pin 2 is also at high potential.
Basically it is a sound activated switch circuit that has a condenser mic that picks up the sound converted in electronic signal and then is passed to the transistor that switches on the led light in this case the 220v light for a period of max 1 minut this is a clap on circuit already designed so we have to just assemble it a more advanced clap on switch will follow in the next episodes.
Oct 13 2016 although its name is clap switch but it can be turned on by any sound of approximately same pitch of clap sound. When you clap once the relay is activated and the light or any load is turned on. When clap the load is switch on and when again clapped then load is switch off. Oct 13 2016 although its name is clap switch but it can be turned on by any sound of approximately same pitch of clap sound.
