Clap On off switch with 4017 IC and BC547 Transistor

This is the circuit of an extremely delicate applaud switch. It switches ON/OFF a White LED or electrical apparatuses through applauds. The circuit can detect the sound of applauds from a separation of 1-3 meters. Condenser Mic gets sound vibrations c by the applaud.

These sounds vibrations are given to the Base purpose of transistor BC 557 (a PNP transistor). It intensifies the sound gathered by the Mic. Transistor authority point is associated with IC point 14 which is clock point. At the point when clock e is gotten from Amplifier Transistor BC557.

IC 4017 is 10 years counter IC which is wired as a flip switch. That its yields 1 and 2 turns out to be high and low when the information stick 14 gets heartbeats. output4 (pin4) is associated with the reset stick 15 so further checking confined. The high yield from IC 4017 goes through resistor to the base of exchanging transistor BC557. At the point when BC557 conducts, Red LED (marker LED) turns on. A 6V 100 ohms hand-off is associated with the focuses denoted (An and B), the hand-off turned on and 220v AC go through the hand-off and bulb or some other electrical machine Switched on. In the following applaud yield stick 2 turns out to be low and hand-off and pointer LED turned off.
