Hi, also a CAD or picture of a hand drawn circuit diagram would also help.
How are you powering your LEDs?
I hope not from the 5V on the arduino board, this is limited in current, and really supplying an array of LEDs is not what it is for.Tom......
Yeah, I'll get you a circuit diagram this afternoon. And no, I am not powering by the 5V, I am powering it by way of Vin which is supplying 12V from a wall wart.
