Applications Of Clapping Switch
- 1. APPLICATIONS 1)This circuit can switch on and off light a fan or a radio etc;by the sound of a clap This circuit is constructed using basic electronic component like resistor transistor relay transformer capacitor .This circuit turns on light for the first clap . the light turns on till the next clap .for the next clap turns off this circuit works with 12v voltage . therefore a step-cown transformer 12v/300ma is employed. The working of the circuit is based on amplifying nature of the transistor . switching the nature of transistor and relay as an electronic switch. 2) What are the different uses of clap switch? it can be used in the case of saving power and time . If we modify this circuit we can use it for security purpose also. Clap Switch Circuit Summary: If you wish to “ON” and “OFF” the device without a penny shifting from your space then this circuit is helpful for you. One more plus point of this circuit is that there is no fear of the electrical shocks as you are not required to touch any of the mechanical switches physically. Visual indication of the devices is also provided to you. With the help of this circuit, speed of the fan can also be controlled by connecting regulator with individual outputs. Clap Switch Circuit Description: Along with some of the other components, this circuit is mainly based on the two ICs i.e. NE555 timer. IC 555 timer in this circuit is wired like a monostable oscillator. For this circuit, IC NE555 monostable produces a clock pulse, which is used to give an oscillating wave at IC1 pin 3 which is an output pin. Monostable (or you can say one shot multivibrator) contains only one steady state and all we need is to trigger it externally to return it in reverse direction to its original state.
