LED strip controller

It can drive an RGB LED strip which can be up to 25 meters long, using music as input. This can come from any device with a line level output (basically all PCs, mobile phones or Hi-Fi systems). It uses a visual equalizer which separates the audio into 3 channels: low, middle and high frequency, and each of these correspond to a specific color. The device also supports passive modes, where no input is needed.
