 | | Using 2 polaroid ultra sonic modules simultaneously...

How would you use two ranging modules on the the same HB simult.? There are two different ways on the HB web site but they both use TIC3 at Dig. Input 7. How else would I be able to implement this? Any help would be greatly appreciated... -- --Peter (...) (25 years ago, 4-Oct-99, to lugnet.robotics.handyboard)

(...) This is a classic application for what is called an Instrumentation Amplifier. An IA functions just like an ordinary Op-Amp, however it typically offers close-to-rail-to-rail outputs and at least a very high input impedance. One would then use (...)

It sounds like your motors could be drawing too much current, and re-setting the board perhaps.

ok I have to read a signal with almost no curent in the mv range and have it so a computer like the hb can detect it. now I dont mean just yes or no. I mean to watch the waves in the mv level and the circut cant distort it. couse dont amps just (...) (25 years ago, 3-Oct-99, to lugnet.robotics.handyboard)

your motor probably draws too much current to work with the HB. unplug the motor and see if things work. if so, the problem is your motor. see the FAQ more for on how to choose a motor that works with the HB. fred In your message you said: (...)
