I am building a free pendulum clock, and am hoping to get pulses at
the rate of one per second from a photoelectric cell in the path of
the pendulum.
Where can I find a circuit which will count these, and give out a
signal after 30 pulses?
This would be used to drive the clock hands, and also power a magnet
to keep the pendulum swinging.
Thanks for any help,
John
