a guy just told me an electret microphone needs power to work
when pluging 1M[ch937] resistor on arduino bt between ground and any analog input, arduino still send continuously values from 1 to 8 for this input
are you sure about what you said for this preamp sheme
The data sheet says the gain should be between 100 and 300 so that is what you will get
If you want to cut it down do it on the input of the arduino with a potential divider coming fro the transistor's collector, don't mess with the front end.
this might be better then
do you mean that to get a lower gain i should add a resistor near c2
i think this would divide voltage output by 2
will it stop clipping at a max value
