# Arduino + Microphone how to grab values?

I have a simple microphone. How can I send some "volume" or "oscillation" values via serial to the computer?

I built a simple preamp but it does not respond, any hints?

If you are just trying to sample a microphone, then an Arduino might not be necessary. The computer has all of the tools required to sample and process data.

For example, if you have the data acquisition toolbox on MATLAB:

ai=analoginput('winsound');
