pke 2 in 1 Clap Swith - Sound Control and Remote Control Circuit Project

Description

Just clap your hands together and watch the Sound Activated Switch turn on the light emitting diode (LED). Clap more and watch the LED turn off. A one-shot, or monostable multivibrator, is a circuit that, once triggered, will switch its output logic level. The output will remain at this new logic level for a predetermined period of time, after which the output will switch back to its previous logic state. This is the core of the Sound Activated Switch.Here is a circuit for electronics hobbyists that can switch on and off a light, a fan or a Radio, etc., by the sound of a clap or any Remote.The sound of clap is received by a small microphone in the circuit. The Relay contact is connected to the powerline and hence turns on/off any electrical device connect at output socket.No Transformer Supplied, No Soldering Iron, No Solder Wire
