A "Clap On Clap Off" switch is an interesting concept that could be used in home automation. It works as a switch which makes devices On and Off by making a clap sound. Although its name is “Clap switch”, but it can be turned ON by any sound of about same pitch of Clap sound. This circuit employs some very simple and cheap circuitry, and a simple program. It is relatively easy to make a hardware only clap on/off circuit, but I wanted to create a circuit that required two claps to switch on, and two claps to switch off.

This will help us to search some objects in the dark, when you are watching TV or lying on bed etc. A Transistor switch, which is used for opening or closing of a circuit, that means the transistor is commonly used as a switch in the electronic devices only for the low voltage applications because of its low power consumption.Transistor work as a switch when it is in cutoff and saturation regions. So when you clap the trigger goes high, the discharge turns on, and output goes low as it has been waiting to do. The edge toggles the flop and the output goes high waiting for the whole thing to repeat. Beside the strange way the 555 is being run, the 7474 doesn't like 9V either. You should find a better circuit.

3) Double Clap-Clap Switch Circuit. All the clap-on switch circuits explained above have the ability to operate only with single alternate clap sounds. This feature makes the circuit vulnerable to external sounds which might occur occasionally triggering the connected load with the circuit. Abstract : The operation is simple. Clap and the lamp turns on. Clap again and it turns off. The electret microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bistable multivibrator change state at each signal.
