Interface mp3 player with arduino

Hi ! I want to let my robot speak. I have an arduino Diecimila and the sound card of the Game Gear : (Don't let attention with the yellow circle ^^) So, I want to know how can i interface this sound card with arduino to just play an pre-saved file ::) Or, can I use an mp3 player like this And connect it to my arduino ? Thank you

I don't know about the game gear thing, you would need a schemtic for it to figure it out.

You could probably hook up to the play and stop buttons on the mp3 player, but it would be difficult to allow for selection of different sound files.

A better solution would be to use this:

I would second that, the wave shield is a good place to start, there are other boards now though if you want to go hunting.

I would also recommend the uMP3 player as a better board with more options:

Thank you for your answer, but I haven't got enought money to buy that shield :'( I don't need change music, just play one when I "tell" arduino to play it. I think I can do it if I disconnect the power button and I replace it by the ANALOG IN from arduino, or something else... Because the music start when MP3 Player start ::)

Ok, using the player you have...

I would recommend that you have the player permanently on, powered when the arduino is powered. Then use a transistor circuit (the transistor controlled by the arduino) in place of the play and stop buttons (and any other buttons you want to use).

Then you could send a HIGH on a digital pin, to simulate pressing the button on the player.

Transistors are a few pence/cents each so you're not going to break the bank with those :D

transistors or will opto-couplers be a better choice? :-/

Maybe opto-couplers but I would have thought that it'd be ok with transistors and they are cheap and easy to use.

Price sensitivity may make the decision :)

Yep maybe...

Transistors:

they are cheap and easy to use.

Opto-couplers: Not quite so cheap and not quite as easy to use (or should that be understand for a beginner)
