I have done the clap switch project but the project was a failure, i could not trace out the problems because i have solder all the components following by the provided diagram (see attachment),
can anyone please help me...!!!
thank you.
Additional information.
when the 9V battery is plug in, LED1 does emit light but when i clap there is no function with the relay.
as u said i have check it out, and my connection is correct..
through multimeter, i got to know that from IC1 pin 3 there is an output to pin4&8, but there is no output from IC2 pin3, and i have also changed the Transistor(2) and all of the IC...
but the result is still negative...
what should i do now?
its a bit difficult to analyse looking at this circuit, without checking various test points practically.
Here basically whats happening is IC1 is triggered in default state itself without clap signal. That means T1 is also triggered.
According to the ckt, T1 should be triggered only when there is a clap signal. or the resistor values are wrong. so ensure that the resistor are of the right values given in the circuit. for eg; you have not put 270Ohms instead of 270K etc.
