| | | Mark, It has been figured out how to get four touch sensors per input. This gives 12 touch sensors if all three inputs are used. Using this approach, a 16 channel Analog MUX can be hooked up. Sensing the four switch lines using Port A and the Output (...) (26 years ago, 8-Jan-99, to lugnet.robotics)

| | | | | (...) Some thoughts on muxing the inputs: The rotation sensor does not mux very well. The sensor only provides analog values that are used to increment or decrement an angle counter in the RCX. If you tried to mux this you would need to change the (...)

| | | | | | Did not look at the rotational sensor close enough. In that case, scalling down the MUX to a 16 channel will free up PORT C. The Rotational sensor or Fiber-optic can use PORT C for rotational input. This assumes that one motor is running the (...) (26 years ago, 8-Jan-99, to lugnet.robotics)

Yes, but using a lever based approach gives a "pure Lego" solution to the problem, which appeals to the Lego purists out there :-) Me personally, I would use the electronic approach you outlined in your email.
