Hi,
I managed to complete this project and tested it with a lamp connected to the output of the relay and it worked fine. I then mounted it into a case connected lamp and power again and now nothing. The Clap LED doesn’t light up to any sound (Like it did before) and clapping doesn’t activated anything.
All soldering is fine and no loose components. I have checked my 12v power supply and this is also OK. I have started testing the circuit with a meter and so far the components are recieving a 12v supply.
Can anyone suggest possible problems/solutions?
