These seem like newbie questions that were probably answered before at some point but I searched and couldn't find anything.
1. Is there a way to set all 14 output pins, or better yet a subset of them, via a bit string. Say I want to set all 14 HIGH. Can I somehow use a shift or some other command to write 11111111111111 and set them all high, or set pin 4-7 high with 00001111000000? Can I set every other pin high from pin 3-8 by using 101010 somehow? You get the idea.
2. Is there a way to disable the on-board LED so I can use pin 13 to drive an external LED?
Thanks as always. The arduino is so cool, I have to ration my time w/it so I can function at work
