 | | QRD1114?
|
|
In the documentation for connecting sensors and actuators to the HB a The Quality Technologies IR reflective optosensors (QRD1114 & QRB1114) were depicted in the example and recommended. Where can these sensors be aquired? Thanks JTW (28 years ago, 5-Feb-97, to lugnet.robotics.handyboard)

(...) Sure. We put "Front" on digital(14) and "Right" on digital(15). And you can have as many as you want that don't interfere with each other. We did something like... contact = digital(14) * 2 + digital(15) to get both sensor results into an (...) (28 years ago, 5-Feb-97, to lugnet.robotics.handyboard)

|

I can't seem to locate the 'how to add a second power supply for a servo' information. I know I read it once, but now that I want to go back and use it of course I can't find it. (duh) Can anyone point me in that direction? Also I could use any (...) (28 years ago, 4-Feb-97, to lugnet.robotics.handyboard)

One of the student groups in my Lego robot course is having a problem getting their Handyboard to work...they got IC to load successfully, then went ahead and installed U6 ('HC138), U9 ('HC04), U5 ('HC244), resistor packs RP1 and RP2, and SW2. Now (...) (28 years ago, 4-Feb-97, to lugnet.robotics.handyboard)

whether you use analog or digital ins, you don't need the 47k pullup because the hb already has one. just wire the signal line to ground through the normally open switch. bill, i suggest you write your program without using the multitasking (...)

(...) Why would you use the analog ports for a bump sensor? Isn't that just a contact switch? Tie to a digital port pulled high with a 47K ohm resistor, and have the normally open contact tie the pin to ground when the contact switch is closed. The (...)

| | Sample bump sensor routine

I am having trouble writing a routine for my bump sensors. Evertime I write a program I can't get the analog ports to initialize. I guess this is where you would connect bump switches isn't it. I can get my bot to go forward, turn, and go backward (...) (28 years ago, 4-Feb-97, to lugnet.robotics.handyboard)

Hi everyone, i was wondering if it's possible to drive more than one infrared LED (emitter) through the handy board and IC. Has anyone tried doing before??? i want to model the wall-following behavior in my car, by using emitter-detector pairs on (...) (28 years ago, 3-Feb-97, to lugnet.robotics.handyboard)
