Clap Switch ON/OFF Circuit Diagram



Description

                 Figure shows the circuit diagram of the ' Clap Switch ON/OFF '. Here  I have used a 4017 ten channel decoder integrated circuit for making this circuit. When you clapping  B1 convert the sound signal into electrical signal and fed to the input of Q1 this time the Q1 is ON so the lamp will glow. Next time repeating  this process but this time the Q1 is ON so the lamp will be OFF.
