Hi guys, I was wondering if anyone of you could help me. I'm trying to connect a hacked version of a Sharp GP1U58Y Ir detector(hacked so it is now analog instead of digital) to the HB so as I could use it for Ir Proximity sensing or distance (...)

IC can't seem to find: /usr/local/lib/ic/lib_r22.lis Is this important? Where is it (not anywhere on my box.) Thanks all. (26 years ago, 22-Feb-99, to lugnet.robotics.handyboard)

Yes there are two four pin connector along the fornt edge of the expansion board that connect to J13 and J8 on HB, one 8 pin (2 rows of four) that connects to jumper J6 on the HB and one 10 pin that plugs into the expansion bus J3 on the HB. Hope (...) (26 years ago, 22-Feb-99, to lugnet.robotics.handyboard)

I promised to update all you ultrasonic types on my progress (or lack thereof) in connecting two sonar modules to the HB. Well, I still haven't figured out if there's a way to connect two sonar module echo lines to the same TIC port on the HB. The (...) (26 years ago, 21-Feb-99, to lugnet.robotics.handyboard)

We assembled the HandyBoard ourselves and everything seemed to go great. However, the new set of analog inputs does not seem to be reading in values correctly. The input always seems to be stuck at 250 (The handyboards inputs still work fine.) I've (...) (26 years ago, 21-Feb-99, to lugnet.robotics.handyboard)

| | Re: IR output
|

You can connect an IR LED to it. Maybe you may need a series resistor to limit the current through it as well. Basically, the IR LED acts as a transmitter (the same round thing in front of your remote). The demodualator is not a transmitter...it is (...)
