CLAP SWITCH :-

                        Here’s a clap switch free from false triggering. To turn on/off any appliance, you just have to clap twice. The circuit changes its output state only when you clap twice within the set time period. Here, you’ve to clap within 3 seconds.

    by watching this circuit diagram you can learn easily how to create a clap switch by using these components.

COMPONENTS USED:-

• resistances-1k,47k,470ohm(2)
• transistors-bc 547(2)
• capacitors-100nf(2),100uf
• ic 555 timer
• mic
• battery
• led.

                               we can build clap switch
