Need assistance getting MP3 shield and proximity sensor to work together.

Hi. I am working on a project utilizing an infrared proximity sensor with the SparkFun MP3 Player Shield.

I have both the sensor data coming in and can play audio through a speaker wired to the MP3 shield successfully, although independently.

Essentially, what I want to end up with is a song that begins playing through the speaker when someone is detected within a certain distance from the proximity sensor. However, I haven't done much coding with Arduino and the little I have was quite a while ago, so any advice as to where to start or how to go about doing this successfully would be greatly appreciated.

I imagine it would involve some sort of code that is the equivalent of, if ir serial input is between X values then play MP3.


EDIT: Just realized I accidentally posted this in the wrong forum. If a mod could move this to the Project Guidance forum that would be great. Sorry!

Start with the example code for the player and add the proximity control code. It is not too difficult.
