The problem is that I copied the code provided from Parallax (below) and I was hoping no modifications are needed for the software. Well, it doesn't work and I am not sure if I have a wiring problem, although there is only 4 wires to hookup, or if I have a software issue. I'll keep playing around with it but I was curious if anyone on this forum has interfaced the PINK module with a Microchip PIC.
