You don't even need a rotation sensor. You could turn a dial, and for
each position a touch sensor is pushed. Ie, for a typical clock
style, you gear things up so that for one rotation of the dial the
touch sensor is pushed 12 times. A ratchet so that the dial turns one
direction only will be helpful. Then a second touch sensor is used as
the "enter" button.
When I was in high school, back when small towns didn't have
computers, a teacher had a simple instruction kit about computation.
It used almost solely relays that could be wired up to form ANDs and
ORs; there were no ICs, transistors, or other "smart" components. One
project on it that completely amazed me at the time as a simple adder.
The input was a dial, and at each position a circuit would close. You
entered two numbers, pushing a button between each. Then the amazing
thing was that the dial would automatically rotate itself with a motor
until it pointed at the correct answer (ie, the circult would close
and turn off the motor). The same effect could be done in Lego, using
the same input dial as the output.

You can model the interface after the cascading menus that many electronic devices have. Basically, (...) (22 years ago, 14-Apr-03, to lugnet.robotics)
