Hi again Audioguru, Yes i am using a 9v battery and the LM358 is installed at the right way, If an electret mic connected Instead of dynamic mic the circuit is not responding and also there is no high temperature at the LM358. Anyway, can you show me how to modify the circuit in order to use an electret mic?

Well here it is, unfortunately, there was no schematic diagram with the KIT so I tried to make it of my own and I hope to be right. I tried to use a dynamic microphone as you told me to do and also a small speaker (0,4w 8ohm) but the circuit it seems to be

Oh audioguru, I guess you are right. Tank you. I am going to test it and then post it back here for the public. By the way, do you know any similar circuit using electret microphone to sagest?

As I can understand, there is not enough input sensitivity from the mic in order to trigger the circuit. When I tried to connect, the input pins A & B (mic input) with a piece of wire then it was working good. What is wrong?
