-- What is MPD?
MPD is a descent challenge to build up own jukebox at
home using PC.
It supports major compressed/uncompressed audio formats and has nice
socket control interface.
-- How powerTunes works?
powerTunes uses powermate as an interface to MPD.
It is capable of showing current playback status(play/idle/pause) of
MPD and gets input from powermate and send it to MPD.
For example, when MPD is playing some song, LED pulses at a steady
speed and when paused, pulse gets faster and when playback is stopped,
LED is lit without pulse.
At a moment, powerTunes supports 4 inputs:
play/pause - short click
stop - long click
next track - rotate clockwise
previous track - rotate unti-clockwise
