I've got a PIC chip programmed with IR collision-detection built
into it (I'm trying to get some of the new 8 pin PICs to see if
I can make an "all in one" unit. Basically the interface is two
bits:
bit 0 output - Turn on IR illumination (double modulated)
bit 1 input - Reflection detected.
The code is a variation on the IR code that is on cher already. So
give me two I/O pins, one in and one out and I can put a reliable
IR detector on it. I can also repeat for 'n' detectors.

| Fred, It seems to me that the first thing most people want to add to their robots that is not supported on the handyboard itself, is IR collission detection. How about including a modulator and driver for IR LED's, and a detector and demodulator (...) (27 years ago, 14-Feb-97, to lugnet.robotics.handyboard)
