I have a couple of prototype angle sensors looking for a good home. (URL) simple devices contain a potentiometer and a small series resistor so they vary from 1k - 11k while the input shaft is rotated through approx. 270 degrees. There is a built in (...)

What would happen if you took a wire from a sensor port on one rcx and connected it to a motor output on another rcx. Would this be a viable way to communicate with 2 rcx's if they could not be position for IR communication? My thought was that you (...) (23 years ago, 28-Sep-02, to lugnet.robotics)
