This is a simple setup connecting 32 RGB LED's with one WS2801 per LED to the SPI interface on arduino. There is two modes selectable in software..
- Display Mode: Which stretches the outer pixels on the screen to the LED's..
- Sound Mode: Which acts as a VU-meter for the sound coming out of the PC.. The left hand-side of the screen will represent the left speaker and the right hand-side will represent the right speaker..
