Hi Kamikaze,

If you want to consider another circuit, goto www.aaroncake.net/circuits and search for SOUND LEVEL METER. Where the input to the bar graph is you could feed that into a PIC analog pin and go from there.

There are many published articles for what you want to do but I think after looking at Darrel's and mine you should be able to accomplish what you are looking to do.

Did you get your other LCD project going? I was referring to using a serial LCD. Sparkfun has one very reasonably priced and very easy to work with.

HTH,
