Operational Amplifier LM324 and super microphone circuit, Afroman goes over the basics of how to use an operational amplifier to amplify tiny voltages, and builds a circuit to listen to very faint sounds with a microphone.
For more information about amplifiers, Google “inverting amplifier” “non-inverting amplifier” “instrumentation amplifier” “class A amplifier” “class B amplifier” “class AB amplifier” and that should give you a lot to chew on.

I put this circuit together but I didn’t have the 5k resistor so I used a 1k resistor. But it didn’t work so I’ll try to find a 5k and test it out again.
Excellent!! Was trying to do exactly this. Get 2V out of a headset mic. Ace vid, and cute cat.

It is very much informative video I gained much knowledge from this website
