How would one use flashing LEDs in a multiplexed array?
My initial, and only, thought at this point is to put a small capacitor in front of the flashing LEDs. The hope being that while the pin is being addressed it would maintain at least a small amount of current through the LED and allow it to cycle on/off.
Does anyone have any issues or suggestions (cap size, type) about this plan? Is there something else that works or will this damage something or cause weird effects? I'm really quite rusty with the RC stuff I learned back in college so I really don't know how the cap will behave with non-constant source.
