Hi
Did anyone receive an answer to this. I ant to connect
a Radio Shack (276-143) IR LED to the IR output and am wondering
what resistance to use. Also, I saw a design in Mobile
Robots..Inspirition where they use two IR LED (one on each side)
and a IS1U60 receiver in the middle as a proximity detector.
Is this possible on the HB? Can one connect two IR LED's
to the HB and move the IS1U60 to the front of a bumber.
Thanks for any advice
Mike Howard

| Is the IR reciever on the HB the same thing as in the robot in MR:ITI book? I though it would be different. In any case, you can but...the reciever is more effective as a "wireless communication" device that can recieve various IR codes which you (...)
