Do you have any specs on the RGB strip and how the host system is connected to it (what are the three output pins connected to on the RGB strip)?

Edit: I guess it doesn't really matter.

I'd start by just reading the analog input and putting that value on the three outputs and verify that he can see a color change based off the pressure input.
I think it's been said a few times in this thread already but he needs to break it down into smaller chunks.
