Hi all
I've successfully used an electret mic to create a clap sensor, like in this circuit. The mic I used was a large-ish thing like in this picture. Everything worked fine.
I bought some electret mics from Amazon and received some much smaller mics than I was expecting (should have checked the dimensions!)
I tracked down a data sheet which seems like the right one, and it seems to require them to be wired up the same as the larger mic. But when I try to amplify it with transistors - like in the clap sensor schematic - the signal seems to just become flat.
I don't really understand how to read the facts and figures in the data sheet, which might help me understand what I might need to do differently.
Can anyone help me understand either how to use these things, or how to read the datasheet to design a successful amplifier to trigger a 555?
Thanks
