If you do not want to be limited to four floors you could have one long rod
with "bumps" at every floor. With something sticking out of the elevator
car, you know you have reached a floor everytime the rod is lifted from the
ground. If you want to be able to set ground 0 to know where to start
counting you can put a sensor under the elevator car so it knows it is on
the ground. You then you need a kind of initialize routine.
Hi -
I'm new here...but I think you are missing something obvious. Why not use a
rotation sensor to determine where the elevator is. Use a touch sensor at
the bottom to set the rotation sensor to zero, and then go from there. It
might take some trial and error to relate the number of rotations to the
actual position, but it is doable and should work quite well.
I think go back to lurking now.
Happy Turkey Day
Jeff
