Introduction: LinkIt ONE- Music Player

Who else loves music? I bet those who do will find this Instructable interesting and fun to do.

Before i start this instructable i would like to thank Instructables to provide me and 249 others a LinkIt ONE board. LinkIt ONE is a arduino compatible developer board. The LinkIt One has built in SD card support and sound. I built this to show school kids the simple yet cool stuffs that can be programmed/made using LinkIt ONE.

In this instructable, i will be guiding you in setting up a mp3 player on your board and playing music via external speakers.

Step 1: Setting Up LinkIt ONE Software

Download Arduino IDE 1.5.6-r2 BETA or 1.5.7 BETA and then the latest SDK of LinkIT . This will install all drivers needed and then you can try running a sample project from SDK to check if all is working well.

For more information you can check out their official webpage here.

Step 2: Hardware Setup

Supplies/Components needed:

1.) SD card.

2.) External audio jack speakers (I have used headphones here).

Step 3: Setting the SD Card

1.)Format your SD card and load songs into it.

2.)Insert the SD card in LinkIt ONE [Make sure your LinktIt ONE is in SD Card readable mode]

3.)Connect your speaker to the LinkIt ONE's audio jack.

Step 4: Testing the Code.

Modify the code depending on your song names and number of songs you have in the SD card.

Right now i don't have a switch/keypad to change the songs, so i'll be using the Serial commands to change it. In the code here, to start a song, ill have to type a number corresponding to the song in the list. The volume here is set to 3. You can change it depending on your preference [max value is 6].

Step 5: Additional

The next step which i would want to add to this later will be a volume controller and a keypad.

The linkIt ONE can be made to run on battery [comes with the board], so this player is more suitable with LinkIt ONE compared to other boards like Intel Edison, Raspberry pi.

Is it necessary to format sd and then adding only song?

Not really. You can do it without formatting it too.
Formatting must makes sure that the unnecessary songs have been removed and maintains a clean directory.
