Description: The LilyPad MP3 Player is your all-in-one audio solution, containing an Arduino-compatible microcontroller, MP3 (and many other formats) audio decoder chip, micro-SD card socket, and a stereo audio amplifier. Part of the Lilypad E-textiles line, this board can be used to give your fabric creations the gift of music, or any other sounds you can put on a micro-SD card.
It can be powered by a 3.7V Lipo battery (charging circuit built-in!), or an external 3.5-6V source. Off the shelf, it will play specific audio files when any of its five trigger inputs are grounded, or you can solder in an RGB rotary encoder (not included) and load new firmware (included in the link below) to add a user interface for track selection and volume control!
The board is compatible with sketches written for the MP3 Player Shield. Our example code uses Bill Porter’s MP3 Player library, which makes writing new code very easy. All you need to do is add a microSD card and some speakers, and you’re ready to rock.
Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features.

I am using the LilyPad MP3 for a custom alarm system. Instead of the usual siren, buzzer or bell, I am using a vocal warning and this device is perfect in this application.
.So compact and easy to use
The LilyPad MP3 can play very loud through 8Ω speakers. Instead of remixing your tunes, you could re-program it to play softer, or add a resistor, variable or not, in line with your speaker(s).
Average batteries last very long. There are some voltage-level concerns with interfacing, but overall the power system is versatile enough for most applications.
I find myself wishing the board were smaller.
The 6-pin FTDI interface is fine for programming but awkward for everyday recharging. If I were to give this to someone, I’d solder on an FTDI basic so that the user was presented with a USB jack for charging.
