Can you suggest some tips or tutorial how connect a SevenSegment Display with properties NumDisplays 4 to Arduino board?
I'm trying to simulate an alarm clock
Thanks

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This is 2 SevenSegment, but is the same idea, segment pins are shared, then you multiplex betwen displays conecting to ground each display common cathode pin.
