This project is to demonstrate a simple mic setup using an omnidirectional microphone (part # POM-2244P-2-R), an Arduino UNO to process the sound and a LED to validate functionality of the output.

The diagram is simple enough to be self-explanatory. The codes for the sketch is below and was develop as a proof of concept only. I am sure they are better ways to accomplish the same. And, as a matter of fact I will welcome improvements to the codes or project in general.
