I would like to use the 7 segment LED counter circuit to count pulses from a shaft of a motor. Can the counter count both up and down? Is there a pin on the BCD counter that tells it to count up or down?
Also how would I be able to detect which way the motor is turning?
Thanks,

I would like to build a counter that would indicate how much anchor line I have out when achoring my boat. The windlass is basically an electric motor with a chainwheel on the shaft. The chain wheel grips the rope and pulls it out of the boat overboard or pulls it up into the boat.
The sensor...
