So I've been imagining connecting an IdPi to my receiver/amp. It occurred to me it would be cool if there was a way to connect an IDPI to some kind of hardware for basic media controls such as play/pause/next track/previous track. That way if someone walked up to my desk and was interrupting my music or I needed to get up I could pause without having to fish my phone out of my pocket and unlock my phone first. Has anybody found a way to do so, either by a bluetooth controller or by a hardware modification of the PI itself?
