Yeah, the analog pin is working after all, it just isn’t nearly as responsive to the music as I expected it to be. Basically, I am trying to sync an LED with the song being played. But it seems like the values are almost random. I even tried a trance song that begins just with a driving bass kick at quarter notes (you know, that typical….bump…bump…bump…bump) and yet the values are not what I had expected nor are they easy to work with. I tried mapping out a range of values to sort of “zoom in” and get a greater range and that made it a little bit better but still…

How would I sync up the song with the LED?
