thanz Duncan for your advice. but for question 1, what i mean was to count the number of pulses generated without any external device. what i am asking is to count the number of pulses internally. and for question 2, i mean is there any command to (...)

Just a suggestion but you could mount a Hall effect sensor somewhere near a rotating rounded part on the cage and glue a small piece of magnet to the rounded part. You could look for the pulse on a digital input. This way it would not add much (...) (26 years ago, 22-Mar-99, to lugnet.robotics.handyboard)

I've rigged up a rotating cage holding the Polaroid 6500 transducer at the front of one of my bots. Every time I turn on the handy board, I'd like the software to begin by centering the transducer facing forward. I've rigged a micro motor to a bevel (...)

Hello. I attempted to use the polaroid sonar device which is plugged into my expansion board on my handy board. I loaded the sonar.c file from the handy board web site using IC. When I called the routines in the sonar.c I got a "tick" sound and an (...) (26 years ago, 22-Mar-99, to lugnet.robotics.handyboard)

hi everybody, i am trying to ask 2 questions. question 1: is there any way to count the no of pulse generate by the handyboard? question 2: can i execute 2 function at the same time?(eg. testdigitals() and testanalogs() at the same time) with (...)

Dear Guys, It just so happens that I remembered that I have four old but still is good condition Ni-MH battery packs from an old cellphone, each pack is rated at 4.8V and 600mAh and the weight of all four of them is just about 75% the weight of the (...)
