Dyne's Audio Modulator Circuit

[Dyne]

I have added a wiki page describing the simple Audio Modulator Circuit that I made for Artie Deco (mostly based on info from the Arduino forums), just in case someone wants to use it on their droids.  It's just a quick and dirty circuit that feeds the audio level back into an analog input on his Artieduino.  I use it to make his neopixel eye flash "in time" with his sound effects.

There are far superior or at least more correct ways to do this, but this is probably the simplest and easiest, requiring the least knowledge of electronics (and I explain how most of it works anyway).

The page is still a work in progress, but a lot of info is there already.  I still need to write more in the coding section, as I need to extract Artie's current code into something self-contained that people can adapt more easily.  I will probably also add more images.  The page has been linked on the main page of the wiki, in the electronics section.

Let me know if anything is unclear.
