Why does it seem like everyone except me needs a pullup resistor and perhaps a capacitor somewhere to operate the Polaroid? I've never had any problems without any of these components. ??? The first time I connected the sensor, it worked perfectly. (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

Has anyone tried to use one of the TI tsl1301 or 1401 linear sensors with the HB. I ended up with a few but am having a tough time trying to figure out what the data sheets are trying to tell me. Not real clear (to me). Bruce A. Moore (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

I am interested in using the Handy Board, but I have a few questions about it first. Please help. :) I noticed the Handy Board supports 4 motors but I am interested in using stepper motors with it. Is this possible? If so what modifications would be (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

Are you using a pullup resistor on the ECHO pin? If not that is your problem. The ECHO output is an open collector driver which requires an 4.7 K pull-up resistor between the output and Vcc. The pull-up is necessary for connecting the module to a (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)

I am trying to use one of the Polaroid 6500 kits from Wirz with my senior design project. It doesn't exactly use a handyboard, but our microcontroller is virtually identical at the lowest level. The problem is when we attach the device to the scope, (...) (26 years ago, 21-Apr-98, to lugnet.robotics.handyboard)
