Hi everyone!

Multi CD emulator is great. But what I want to do is make it work with my mp3 player. I don't require RS232 connection, I would just want to send 1/0 signals to the various mp3 buttons. For example, connect mp3 buttons next/play/pause/previous/ to the lets say AT89C controller, so that I can control them on simple way turning on and off appropriate At89C outputs.

So, what I'm intersted in is there any schematic how to "convert" Multi-CD emulator to this?

PS. Sorry if this has been solved already, but I don't understand Russian
