The Shifty VU Shield accepts stereo audio from a computer, CD player, or other audio source. A ShiftBrite header is provided, allowing the Shifty VU shield to visualize the input audio levels on a chain of RGB LED modules. Using the Arduino IDE, any LED visual effect can be synchronized with music or other audio. Stereo audio is filtered and rectified, providing analog values on A2 and A3 that correspond to the average audio volume.

The shield uses the hardware SPI pins, making it incompatible with the Ethernet Shield and possibly other shields that use SPI. It is also incompatible with the Arduino Mega in hardware accelerated mode, but will still work in software mode. Since the SPI pins are merely an electrical connection to the ShiftBrite header, they will not interfere with any other shields if the ShiftBrite header is not connected to anything; in this case, the shield simply provides filtered audio on A2 and A3.
