SET YOUR POWER SUPPLY to 4.5 VOLTS or you will DESTROY the DAISY!!!!!!!

 

/* This sketch is for using the Daisy Mp3 player in Four Four mode with your Arduino.

Toggle through sound files using a pushbutton interface.

Each time the button is pushed, a new song plays.

 

IMPORTANT: All mp3 files must be labeled 00001.mp3, 00002.mp3... or they will not playback.

 

The sequence of sound files can be randomized.

See the Arduino Reference page to learn about random(): http://arduino.cc/en/Reference/Random

 

The Daisy Mp3 player will only work with an SD card, or a MMC card, that is formatted as FAT32.

My Macintosh computer performed this function using Disk Utilites, and erasing the card with MS-DOS format.

 

The SD card in the Daisy can be removed by gently pressing it inward (it then pops out). Gently depress the center of the card to transform it into a USB stick that you can insert into your USB port. Now  you can upload your own sound files from your computer to the SD card.

 

Experiment with and modify the following code.

For example, try adding a distance sensor to trigger different sounds from different distances.

Change the number of tracks by playing with the math of the songcounter.
