Clap switch
Keeping in mind the end goal to do an applaud switch, we need to consolidate the touch sensor(monostable method of 555 and the transistorized dull sensor circuits. At whatever point there is uproarious sound created close to the electret condenser mic, pin 2 of 555 gets activated and it switches on theLED D1. The Drove stays on for a distinct time controlled by R1 and C1. We can modify the affectability of the circuit utilizing a variable resistor as a part of spot of settled resistor R5. You can check the circuit with 1K or 10K.
