Description: In this clap switch we use three different modules given below. It is necessary to make these three modules in order to make a clap switch.
Now, follow these steps:
Remove LDR and resistor 4.7K (connected between Pin 2 and GND) from 555 timer based dark sensor circuit(given above).
Step 2: Connect a 0.1uF(100nF) capacitor to pin 2 of 555 and collector pin of transistor Q2.
Step 3: Remove LDR from ’2 transistors module’ and connect an electret microphone. HOW TO CONNECT AN ELECTRET MICROPHONE?
THIS MAKES A BASIC CLAP SWITCH. Change the values of resistor and capacitor on 555 timer to change the timing of the circuit.
PLEASE IGNORE THE REPEATED NAMES OF COMPONENTS. TRY TO SEE THE PROJECT IN SEPARATE MODULES

CLAP SWITCH USING TOGGLE SWITCH
Using a toggle switch in the clap switch would offer two stable states for the circuit. On first clap, the circuit switches ON and on another clap, it switches OFF. However, for that, the resistor and capacitor of the monostable mode circuit should be set in such a way that it short pulse of 1 seconds only.
The Monostable circuit given on this page is suitable for the next clap switch circuit.
