What is the smallest difference between voltages that the HB can differentiate between at its analogue inputs.I am very grateful for the information which has already been supplied in reponse to my queries and have found it useful though not (...)

Hi. I also have the problem of twitchy servos, but I am currently only using one of them. The servo is used in steering and it constantly twitches. Although, when I have nothing else hooked up to the board and have only the servo running, no twitch. (...) (28 years ago, 18-Jan-97, to lugnet.robotics.handyboard)

(...) The Polaroid sensor (50-60 KHz, 1.5-30 feet but maybe more from the air?) is $49 (minumum two) direct from Polaroid. They are in the FAQ or I can look up the ordering stuff if you are interested. There is plenty of documentation for using the (...) (28 years ago, 18-Jan-97, to lugnet.robotics.handyboard)

I just read in Nuts & Volts about your triumph!! What an impressive feat! Doesn't it get boring having your robots beat the competition 15 to zip? Just kidding.. I can imagine the excitement you all must have felt to see your creation take off seem (...) (28 years ago, 18-Jan-97, to lugnet.robotics.handyboard)

Hi, Richard wrote: - but I just read yesterday on a web page that servos want a signal (20 ms = ?? degrees) every 50 milliseconds or so Right concept, wrong numbers. Servos want to see a pulse about once every 20ms. The pulse should be in the range (...) (28 years ago, 17-Jan-97, to lugnet.robotics.handyboard)

Would someone be able to tell me whether the analogue inputs on the HB are sensitive only to voltage or to current.I would also like to know whether or not I could recieve sensor input on more than one analogue input simultaneously and make the HB (...)

If you go to the following link: ftp://cher.media.mit.../cmcmanis/ You will find a file called ir.tar.Z which describes some software I wrote for a PIC chip that drove several LEDs and monitored three IR sensors (Sharp 1SU60s but could have as (...)

(...) Try running the two-servo code, but unplugging each of the two servos, in turn. One servo plugged in to the two servo code should narrow down whether this is a software or power problem. If it only jitters when both are plugged in, I'd (...) (28 years ago, 17-Jan-97, to lugnet.robotics.handyboard)
