thanz Duncan for your advice. but for question 1, what i mean was to count the number of pulses generated without any external device. what i am asking is to count the number of pulses internally. and for question 2, i mean is there any command to (...)

Just a suggestion but you could mount a Hall effect sensor somewhere near a rotating rounded part on the cage and glue a small piece of magnet to the rounded part. You could look for the pulse on a digital input. This way it would not add much (...) (26 years ago, 22-Mar-99, to lugnet.robotics.handyboard)
