please give me clap controlled appliance pdf

Summary of Clap Switch Circuit:

• If you want to "ON" and "OFF" the device without a penny changing its space then this circuit is useful for you.
• One more point of this circuit is that there is no fear of electric shocks, as it is not required to touch any of the mechanical switches physically.
• Visual indication of devices is also provided.
• With the help of this circuit, the fan speed can also be controlled by connecting the controller to individual outputs.

Clap Switch Circuit description:



Along with some of the other components, this circuit is mainly based on the two integrated circuits, ie NE555 timer together with CD4017.

IC 555 timer in this circuit is wired as a monostable oscillator. For this circuit, IC monostable NE555 produces a clock pulse, which is used to give an oscillating wave at IC1 pin 3 which is an output pin. Monostable (or can be called a multivibrator trigger) contains only a steady state and all we need is to activate it externally to return it in the opposite direction to its original state.

Another is the CD4017 which is a CMOS counter / IC splitter. Receives a clock signal through the clock input and sequentially turns on all 10 outputs, each time it receives the clock input pulse.

To familiarize yourself with the operation of the IC, it is essential that you become familiar with each IC pin. These integrated circuits consist of 3 input pins together with 10 output pins also have one ground pin and one more for the power supply and one more pin to carry out.
