For a project (a ghost house -don't ask!) I want to use 8 or so LEDS that come on and go off apparently at random. Sometimes they are all on at once, sometimes none. Some flash, some fade. I think I understand how to program ONE led to do this, but how can I get the arduino multi-tasking, i.e. controlling led 2,3 etc, independently of what it's doing with led 1? Is this what is called multiplexing, or are my wires twisted here? Bear with me please, I am new to this game and can remember when television was black and white, and only available in the better neighbourhoods...
