Sorry for double-posting, but I am having problems with my circuit.
I bought all the parts needed for the circuit posted earlier (http://circuitdiagram.net/simple-mic-pre-amp-based-lm358.html
), except no potentiometer since I don't need one, and a LM386N instead of an LM358.
However, my microphone has 3 wires and not 2. I've read that the two-wire mics have the power and output linked together. Does anyone know if it is it possible to make a preamp with these parts? Or do I have to build a different circuit with different parts?
When first learning something new I usually aim high so I can progress more quickly, but this time I may have bitten off more than I can chew.
I've been researching for several hours now, but can't find anything conclusive (that I can understand anyway), so I don't want to finish a circuit only to fry everything. I don't have enough money to buy a ton of replacement Arduinos and components, so I'd rather get it right the first time.
Thanks to anyone that can help!
