What exactly does common cathode mean in terms of a seven segment display. Im trying to display numbers on a 7-segment that i placed on a breadboard . Im using a 7493 binary counter through a 7447 bcd to seven segment display decoder, but all im getting is weird readings on the 7-segment. How do i wire this?? Does the counter have to be negative edge or use a diff decoder??
