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
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.
