What is a clap switch circuit?

Definition: A clap switch is an electronic circuit, which controls electrical appliances like a bulb, tube lights, etc with user clapping action. It is mainly useful for a person who cannot move his legs. The clap switch circuit can be designed in two ways using 555 IC and without using a 555IC.

How does a clap switch work?

A Clap Switch circuit uses a microphone within the circuit to detect noises to turn the LED on. A clap switch circuit can be used in homes and businesses to turn on things such as: lights, TVs, or whatever it is set up to the clap switch. In many cases you can snap your fingers, clap your hands, or even speak to it.

How do you make a 555 clap switch?

Connection

  1. Connect Pin 4 & 8 of 555 timer to VCC.
  2. Connect Pin1 of 555 timer To GND.
  3. Use a jumper wire to connect Pin 6 & Pin 2 of 555 timer.
  4. Connect Indicating LED at Pin 3 with 220 Ω resistor.
  5. Connect 100K Ω resistor between Pin 7 of 555 timer & VCC.
  6. Use 10uF Electrolytic Capacitor to connect Pin 2 of 555 timer to GND.

Who invented clap?

The exact beginning of applause is a little uncertain, but we know it was first documented in the third century B.C., with the works of Roman playwright Plautus ending with the word plaudite, a directive for the audience to applaud or clap.

How do you make a clap switch with IC 555?

How do you make your lights turn on when you clap?

Connect your appliances to the 2 clap or 3 clap outlet, then activate each one with 2 claps or 3 claps. Light glow in sequence when proper claps are detected. Adjust for softer or louder claps. In away setting, connected appliances will turn on with the detection of any sound.

What kind of circuit is a clap switch?

Although its name is “ Clap switch ”, but it can be turned ON by any sound of approximately same pitch of Clap sound. The main component of this clap switch circuit is the Electric Condenser Mic, which has been used as a sound sensor.

Who was the inventor of the clap switch?

It was invented by R Carlile, Stevens, and E Dale Reamer on 20th February 1996. The main advantage of this technology is that it is mainly helpful for a mobility-impaired person.

How does a condenser mic work in a clap switch?

The condenser mic is one of the main components in the circuit that tracks the input clap sound based on the pitch of clap and transduces this sound energy into some electric pulses. These electric pulses are the desired input to the clap switch circuit. This article gives an overview of the clap switch.

How is a 555 IC used in a clap switch?

As soon as the transistor becomes ON, the potential at Point A would become low and it will trigger the 555 IC because of the low voltage (below Vcc/3) at Trigger Pin 2 and LED will turn ON. We have connected the LED to Output PIN 3 of 555 IC through a 220ohm resistor.
