Using the SFEMP3Shield Library The SFEMP3Shield Arduino library – written collaboratively by Bill Porter, Michael Flaga, ddz, and Wade Brainerd – is an AMAZING resource for the MP3 Player Shield. Much of this code was grabbed from the FilePlayer example included with the SFEMP3Shield library. You could use a switch, of which there are tons of options, or you could just us a simple jumper wire to ground one of the trigger pins. Whew! The shield does use up quite a few pins, but here are the pins still available to connect to other components. They’re not required for most MP3-playing functions, including the examples we’ll show in this tutorial. To disable either of those pins, a jumper next to their label can be cut using a hobby knife. You can connect any of these trigger pins up to all kinds of buttons or switches, or just use a strand of wire to momentarily short them to ground.

Aside from sticking the shield on your Arduino, you’ll need to find something to trigger the pins. Resources and Going Further The tutorial’s over, but there are still plenty of resources to help you get the most out of your MP3 Player Shield: Going Further Your MP3 Player Shield is all hooked up! Finally, before loading the audio files onto your SD card, you’ll need to modify their names. The VLSI app note has some recommended circuits (see sections 3.1 and 3.2) to help avoid this kind of problem.
