Right now the best thing you can do is find examples, play with them, learn from them and make your own code. If you have any issues, let us know, but to get help, you must present a code with comments and put some effort into it.
Sound good. I realize I can't rely on people on the forum to just write the code for me. I'll go play with the examples and come back to the code forum when I have something a little more concrete.
Do you have any idea on how the MP3 Player will interact with the arduino? Have you worked that out already?
Otherwise you'll need to hack it to get at the information somehow, so you can sync the Arduino with the MP3 Player.
The arduino won't interact with the MP3 player at all. I am making a recording that asks a question and gives ABC or D answers. The correct answer to each question will be stored on the Arduino. The game will rely on the people being on the right question.
