Clap Switch Light Circuit Diagram. Initially the transistor is in off state because there is not enough 0 7v base emitter voltage to turn it on. Circuit diagram its working an electronic device that can control light appliances by users clap action is a clap switch.
Condenser mic basically converts sound energy into electrical energy that in turns used to trigger ic 4017 through a transistor this is the simplest clap switch circuit diagram. Clap switch circuit diagram. The ic is working in monostable mode here.
You can see the circuits and connections in the above schematic diagram of clap switch.
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. You can switch on and switch off the appliance at your room by simple clapping or by a sound. Initially the transistor is in off state because there is not enough 0 7v base emitter voltage to turn it on. The main advantage of this technology is that it is mainly helpful for a mobility impaired person.
