BTW, the MP3 module is an MD-FLY. Very easy commands, but I intend to throw together a library for it anyway since I didn't find one. Would be useful to me later since I have several of these boards.
One thing I can't do with this module is read a text file (or any file besides an MP3) which would store the animation commands. But, it does play stereo and I only need need mono. My plan is to set it up so that I have the audio on the right channel, and encoded control data on the left channel.
I think that the code, circuit, and encoder program would be useful for other projects and to other people. So I will be posting that once it is complete.
I attached the spec sheet for the MP3 module. The audio power at full volume is 200mVpp so an amplifier will be needed for a decent volume on a speaker.
