Sweater and MP3 Player Code

Arduino
This file has two sections, so look for the /*BREAK HERE*/ line that separates the two files: the bluetooth sweater code that should run on the Flora, and the LilyPad Mp3 player that triggers the first two tracks on digital HIGH and uses T3 as a cancel button. You'll need a micro SD card with 1.mp3 and 2.mp3 on it.
You may have to dig around a bit for a LilyPad Mp3 library and SDFat library that works with this code.

    APPLICATION SETTINGS

  FACTORYRESET_ENABLE     Perform a factory reset when running this sketch
 
                            Enabling this will put your Bluefruit LE module
                              in a 'known good' state and clear any config
                              data set in previous sketches or projects, so
                            running this at least once is a good idea.
 
                            When deploying your project, however, you will
                              want to disable factory reset by setting this
                              value to 0. If you are making changes to your
                            Bluefruit LE device via AT commands, and those
                              changes aren't persisting across resets, this
                              is the reason why. Factory reset will erase
                              the non-volatile memory where config data is
                              stored, setting it back to factory default
                              values.
   
                            Some sketches that require you to bond to a
                              central device (HID mouse, keyboard, etc.)
                              won't work at all with this feature enabled
                              since the factory reset will clear all of the
                              bonding data stored on the chip, meaning the
                              central device won't be able to reconnect.
    MINIMUM_FIRMWARE_VERSION  Minimum firmware version to have some new features
    MODE_LED_BEHAVIOUR        LED activity, valid options are
                              "DISABLE" or "MODE" or "BLEUART" or
