Clap switch using three modules on mini breadboards

All big electronic projects are combination of small projects. To clarify that I have made a simple clap switch that uses three independent mini projects. Step 1:
make a dark sensor Step 2: Make another dark sensor using NE555 timer(Monostable Circuit) Step 3: Make a toggle switch

After making these three projects, just remove LDR from the step 1 project and place an electret microphone and combine three modules to make a clap switch(as shown in the circuit layout). visit for this project
