Basicly, what I want is a button, switch or whatever on my model that when moved one way causes one input to be sent to the RCX but when moved differently it causes a different input to be sent to the RCX. Should also have a 3rd "off" state. I am going to use it on my RCX controlled tank. RCX will use 2 touch sensors plus 1 motor to drive treads forward or back, touch sensors will trigger if it bumps into something. The "switch" I need will controll second motor attached to a large turntable to rotate turret.

(...) Use a resistor to make one of the states of the switch read less than a full short. Setup as a light sensor. 0 means off 50~ means one state and 100 means another. This is the basis for alot of the touch sensor multipliers. I am sure if you (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)
