This comes from the original LEGO TC Logo materials (1980s) and was used as
a counting wheel. You could use it as a rotation sensor by counting the
number of seperations between black and white. It could also be used as an
angle sensor. You could also program your device to count the number of
rotations over time to determine speed. It was used in conjunction with the
original interface boxes which were at that time tethered to the computer
through ribbon cables and slot cards.
It works on the old 4.5v system and probably cannot be used with anything
Mindstorms.
