08-19-2009, 09:54 AM
I got a WELCOME board from visha kit at IIT as prize.
It got a board with LED to put on in series there is a common 12+ rail but i am changing it to ground by reversing led.
So there are max 15 led in each letter and there will be a moment when all 70+ led will light up.

How do i do it on arduino to make like animated sign instead of provided (second) control board
