How do I use it?

All instructions performed with an Arduino Uno with a 16x ring of WS2812 Neopixels

Make sure the Arduino is set up. At the moment, the data in slot is set to slot 6 on the Arduino.

Select an MP3 file and close the extra window that opens up (this is a consequence of making a last-minute inclusion of GTK into a Console application in an attempt to keep cross-platform compatibility) The audio should begin playing out of your default audio device, and you should see the Neopixel array light up and change colour with the music. That's about it!
