Does anyone know where to get good motors that work good with the handyboard. I need geared DC motors because we dont want our project to be a racing car. If anyone has any answers or suggestions please email me back. Thanks. TIM ===== (25 years ago, 8-Oct-99, to lugnet.robotics.handyboard)

Hi all! I recently got hold of a sharp GP2D12 ir range sensor (The analog version, not 8-bit serial) Upon connecting it to my handyboard (Vcc-5v, Gnd-Gnd, and Vo to analog port) I get between 249 and about 251 value from the analog port. Clearly no (...) (25 years ago, 8-Oct-99, to lugnet.robotics.handyboard)

|

We're trying to use the little radio shack IR transmitter and reciever units to build our own. We're not sure exactly how this will work, but before we get too far, is this a reasonable thing to do? Will these be strong enough to use as proximity (...) (25 years ago, 7-Oct-99, to lugnet.robotics.handyboard)

(...) [snip] Andrew, Take a peek at (URL) and bonk on the IRPD project. Getting IR demodulators to work reliably is a bit more tricky that just looking for a bounce. I have done a LOT of work in that area and have found that you really need to take (...) (25 years ago, 7-Oct-99, to lugnet.robotics.handyboard)

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 (...)

| | IR question
|

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 (...)
