Arduino+MP3 Shield for Car MP3 Player - Need Help

Community Projects
1

The idea has been simmering for a while, and with the holidays upon us, I’m after building an MP3 car player, to be connected to the AUX input of my minivan.

Here is what I have so far:

  1. Arduino Uno R3 (also got a sparkfun red board coming in the mail)

  2. SparkFun MP3 shield

  3. SparkFun Musical Shield

  4. SParkfun micro-SD card shield

  5. micro-SD card, … etc

I’m thinking the combination 1+2 should suffice, otherwise 1+3+4 is an option.

The idea (plan) is for the set to connect to the AUX input of my car, so that playing the MP3 songs can be done directly from the existing audio console.

Has anyone tried something like this? Any help would be appreciated.
