OK maybe a dumb question but I have to ask anyway. You do have a common ground wire connected between the arduino and the PIC, correct?

I think the point is that the pin marked "Input to Pic" should Not be grounded as it is also the output pin from the Arduino and would defeat the circuits proper operation.
