Afternoon, What would be the best / easiest way to control an array of 1,280 (or a large number. More than a few anyway) LEDs so I can tell each LED to be off, on, 33% or 66%?
Would it be PMW control or having three circuits, each with a different voltage, or is there a way to vary resistance? I don't really know, that's why I'm asking.
I have an Idea, but I don't know how to go about it.
