So you could have 6 extra leds if you wanted. Actually, he can't, because he is using common anode LEDs - eight of them. That's why I pointed out that the simplest arrangement is two Charlieplexed "banks" of four by three, totalling eight control lines.

WebMay 6, 2024 · Its not massively efficient because it uses a 1:8 multiplex ratio. In theory two leds could be lit simultaneously without overloading any pin, achieving a 1:4 multiplex, which would be brighter. For example led A could be lit at the same time as G, because to light A, you would set pin 1 low and pin 2 high. At the same time, if pin 3 was high ...
