Using the Shades Audio Sensor without RGB Shades

While the Shades Audio Sensor was designed to work with the RGB Shades, it's really just a breakout board for the MSGEQ7 spectrum analyzer chip. It also has a microphone, pre-amplifier, and gain switch to select high and low sensitivity modes. We've gone through a number of revisions of the hardware, mostly fine-tuning the power supply filtering to make the Shades Audio Sensor reject most of the power supply noise caused by LED applications.

Here's a video showing how to connect the Shades Audio Sensor to an Arduino UNO. We're using a ShiftBrite Shield, but any proto shield or a simple breadboarded circuit would work. As a demo of the finished project, we've connected it to an old ShiftBrite project (Rusty VU) from 2008.
