total NOOB here. trying to make a simple LED sign for my wife for mothers day. So it says: HAPPY MOTHERS DAY! Lighting each character separtely or whatever. So I don't need to control each led separately, just each character separately. So what I don't how to do is add current so that each letter…

How do I add more current to an output?
