While you are sitting in your drawing room and you want to switch on or off the light, you have to move to the switch board and then only you can on or off the light. But what if someone tells you that you can do the same task by just clapping your hand then it seems like a magic?
I designed this project in 11th Standard. The basic components behind this project were commonly available in the market.
When anybody claps, the transducer(MIC) convers the sound energy into electrical energy. This electrical signals are now amplified as the obtained electrical signals are too weak. Now the amplified signals through the electronic circuit trigger the relay. Relay is a type of electro-mechanical switch and this gives switching to the AC supply and hence the light glows.
