Sparkfun Electronics LilyPad MP3, Getting Started

Page: 15 / 28

The "Player" sketch is not preprogrammed onto the LilyPad MP3 Player, but you can easily install it
using the free Arduino IDE. It is included with the LilyPad MP3 software that you can download from
the
GitHub page .
The Player sketch turns the LilyPad MP3 Player into a "real" audio player, allowing you to easily
switch between tracks and change the volume. The user interface is a
rotary encoder (a knob with a
built-in pushbutton) available separately from SparkFun.com that you can solder onto the LilyPad
MP3 Player board.
If you plan on using the player sketch and rotary encoder, be sure to install the rotary encoder
before
sewing the LilyPad MP3 Player into your project. This because you'll need access to the
back of the board to install the encoder.
Required Materials
RGB Rotary Encoder
Clear Plastic Knob (Optional)
Soldering tools
( soldering tools (i.e. soldering iron, solder, safety glasses, etc.))
A single-cell (3.7V) Lipo battery (500mAh or above recommended. You can use smaller ones
if you reduce the charge rate, see the instructions here ).
A 5V FTDI BOB or cable (to recharge the battery and reprogram the board if desired).
One or two 4 or 8-ohm speakers , surface transducers or headphones with a 1/8" stereo jack. If
you want to connect the LilyPad MP3 Player to an amplifier, see this note .
Conductive thread and sewing supplies , or hook-up wire and soldering tools . ( TIP: alligator
cables are a great way to quickly test out circuits and programming before committing to
needle and thread!)
A micro-SD card .
Some audio files you'd like to play. The LilyPad MP3 Player can play many audio formats, you
