Hi Bill, Are you able to transmit IR beams through more than one LED (eventhough the handy board has only one LED driver port). If this is part of your IC code, could u please mail it to the net. Thanks Sriram (28 years ago, 15-Feb-97, to lugnet.robotics.handyboard)

(...) 3v toy motors are noisy little buggers and were never designed to be anywhere near a microprocessor. if you reduced the hb motor battery supply to 3v, you might have a chance. at 9v, i really doubt it. -f (...) (28 years ago, 15-Feb-97, to lugnet.robotics.handyboard)

To measure current with an multimeter or ammeter (volt/ohm/etc.. meter) you must break the circuit at some point and put the meter in series with the circuit thus gapping the break. ie) +-----(+) METER (-)------+ | | | | (+) | POWER | (-) | | | | | (...)

Guys, I caught the mail on motors (3V etc.) and wasn't impressed. I just bought one of those Bulldozer Kits from Tamiya and I believe it contains 3V motors. Is there NO possible way of using these motors??? I did notice the HB motor driver chip (...) (28 years ago, 15-Feb-97, to lugnet.robotics.handyboard)

(...) I can vouch for this technique, this is basically what I do in my PIC program (except the randomness which is a nice touch BTW) and get rock solid detections.
