newbie question

Hi!

I wonder how I can measure sound levels from a microphone using Stamp?
I connected a voltmeter to my mic, and when I yell into it I get a few millivolts difference.

How can I connect a mic to the stamp and measure sound levels?

Thanks

I tried the PULSIN and its actually working, but I have to scream into the microphone to get any response.

Can I use an opamp to increase the signal? I looked at the datasheet for the LM324 which I had laying around, and found this schematic.
Am I on the right track?
