The controller 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 and Hi-Fi ...

This is a where a Power Mosfet comes in. With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips” ...

This setup allowed [Alex] to control all 128 LED’s with just seven bits, but it was too slow for him. His solution was to control the multiplexers with counter IC’s.
