Shared anodes and cathodes are a common technique used to control lots of LEDs with a small number of microcontroller pins. I’m going to talk about why share anodes and/or cathodes. Then I’ll show an example of shared anodes, an example of shared cathodes, and finally combine the two for some more impressive results.
