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 (...)

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)
