Winamp Controller (090531-71)
A variety of remote control devices for Winamp and other PC-based media players have been available for a good while. All of these systems have one thing in common, which is that they are limited to buttons or keys or use virtual progress bars on the computer monitor. If you want to have a complete hardware interface unit with the same level of sophistication as the virtual Winamp design, you need a physical progress bar. In this project a small ATmega microcontroller uses the USB interface to provide a bidirectional link between the Winamp software and a hardware studio fader, which acts as a combined indicator and entry device.
