hi,
The most simple way is to use a sensitive lever type micro switch in the coin slot.
Connect the motor via the micro switch contacts and power supply
Basicly you put a coin in it activates thee notor to turn 4 rotations then when he motor is at the bottom it stops,
after that you need to press the wind up button and the motor will do 4 rotations upwards

Yes; you'll want either mechanical limit switches as suggested, or some way of sensing when the motor reaches its limit, like current sensing (stop when current starts going high as motor stalls). You don't want to just mindlessly count revolutions with a timer or counter, because Murphy's Law says that your count won't correspond to physical reality. You need mechanical feedback, since it's a mechanical device.
