Hey, I just wanted to thank everybody for there help with this, it did turn out to be the pull up resistor problem, I feel like a moron. We used the handyboardy sonar interfacing schematic when we wired it up and failed to realize that we aren't (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

I was wondering if anyone out there could send me some very basic, easy to understand programs that could help me figure out how to use sonar modules. Thanks, Richard (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

Generally the capacitor is the problem :-) The capacitor in the original note is there to pull BINH true* to allow the sensor to detect things that are closer than 18". Generally, when you include it, unless the design of the system holding the (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

(...) Are you using the "smooth" PWM motor routines? Note also, that a DC motor does not change velocity linearly with an increase in current unless it is under load. This was a recently asked question on the list. Maybe grepping the digest for (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

(...) residual noise? It was my understanding that the Polaroid module used pulse time differentials to relay distance information. One need only look at the difference in time, between the leading edge of the init pulse, and the leading edge of the (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)
