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.

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.
