I'm making a digital clock out of a crystal oscillator, and 7490 counters in cascade (also some 7447, BCD to 7 seg).
I think I can handle it, but I'm having problems at choosing the hour setting mechanism.. I thought of simple pushbutton/ interrupt, but I'm afraid of "bouncing effect"... Any ideas please??
