#79209 - RE: led display
Responding to: ???'s previous message
Remember that when driving led by matrix the intersection (led) will be on when the two sides are on.

Decade counter just put a 1 logic by gate, so just one led or one column can be on. You must have all the control over the outputs to turn on and off leds.
