you won't be able to easily) get distance measures with standard IR comms parts (such as the IS1u60). light travels too fast for the time delay betw xmit and rcv to tell you anything. as a proximity sensor, all you get is a yes/no reading. if you (...)

hello all, quick question- inside the Handy Board Tech. Ref. we saw two IR sensors mentioned (Quality Tech. QRD 1114 & QRB 1114). we are wondering if anyone has used these sensors and knows how to obtain them? we have contacted our HB vendor, but (...)

Andrew - - Take a look at Dennis' IRPD ... it uses a 12C508, 2 IR LEDs and a Sharp detector ... works great with the HandyBoard and off loads much of the processing to the PIC. If you want to do it with the HB, then do a search on IRPD and you'll (...) (25 years ago, 7-Oct-99, to lugnet.robotics.handyboard)

Interactive C can't handle 2D or 3D arrays.... instead another method needs to be used.. If your matrix was a 3X3 789 456 123 and rows went from bottom to top and columns from left to right then you'd have to come up with a formula using the row and (...)

I'm trying to set up either one or preferably two near infra red proximity detectors. I'm wondering whether the sharp IS1U60L component mounted on the handy-board is suitable for this type of application. We managed to make it work recieving codes (...)

I need to transfer the data in a matrix on the HB to my win98 PC? I know a special program is necessary to interpret the signals going to the COM port. Does anyone have such a program or have the have some code that I can compile with VS 6.0? Here (...) (25 years ago, 6-Oct-99, to lugnet.robotics.handyboard)
