SOUND CONTROL HOME AUTOMATION

This is a sound control home automation project that uses to turn on or off any electrical circuit. circuit works by creating from distance. When person claps makes can be caught condenser microphone, the circuit's output light turns on. If another claps, will off. The basic idea behind this microphone catches up your coughs, and of book being knocked table. It generates weak signal amplified transistor stage follows. Each changes state two transistors coupled in bistable multivibrator. One these controls bulb through heavier transistor. sound-activated switch. Sound, for example, may used fan, fluorescent light, television, other equipment.
