A clap switch suite is a kit that allows you to build a device that can be turned on or off by clapping your hands. A clap switch typically consists of a microphone or sound sensor that detects the sound of a clap, and an electronic circuit that uses this signal to control a device such as a light or an appliance.

A clap switch suite is a set of components and instructions that allow you to build a clap switch from scratch. The suite typically includes a microphone or sound sensor, a microcontroller or other electronic components, and a circuit board or breadboard for building the circuit.

To use a clap switch suite, you will need to follow the instructions provided to assemble the components and build the clap switch circuit. This may involve soldering components to a circuit board, connecting wires between components, and programming the microcontroller. Once the clap switch is built and assembled, you can use it to control a device by clapping your hands.

 

 

The circuit is mainly composed by audio frequency and bistable tigger circuit. 

 

Q1 and Q2 form the secondary amplifier circuit. Audio signal which accepted by MK1 enters to Q1 base through the coupling of C1, and enters to Q2 base through collector directly after amplified. It will obtain a negative square-wave which is used to trigger the bistable circuit from Q2's collector. 

R1 and C1 restrict the frequency response of circuit to 3kHz which is in a high sensitivity range. Q4 is cutoff, while Q3 is saturated and D3 is off when the power is on. When MK1 obtains the control signal, a negative square-wave has been outputted after amplified and negative pluse has been added to Q3 base through D1 after differentiation processing. The power flips rapidly and D3 is lighted at this time. The power flips again when MK1 obtains the control signal at the second time. And the D3 is off. A cable terminal J1 can be added on PCB which used for connecting external control equipment. It can realize the sound control function on other equipment by connecting J1 and relay. 

(A diode should be connected reversely at the ends of relay when connecting the relay)

 

This circuit uses a 5V power supply. LED is off when the machine current is 3 mA, while the LED is on when the current is 6 mA.
