Toggable MP3 player to play/pause with a electrical input?
I know the title does a poor job of explaining my situation. Basically, what I want to do is make a simple one song MP3 player that will play when it has power, and not when it doesn't. But verses most MP3 players, I would want this to pause when it does not get power, not stop and then restart. I know I need a power source to the MP3 player to keep it's spot in the song when it's paused, but it's critical it has a play/pause function that is dealt with through a power source going to/through it.
