well mathematically, it doesnt seem right, i just want to confirm that the statement is true, because if the math of an led is right, you dont want 5v going into it with 10mA. But if the IO automatically lowers it correctly, then ill be ok, i just wanted to make sure i was reading it correctly. i guess i am, thanks for the help. rep is on the way.

im a little pushy today, just a long rough day personally and with work(school).

thanks again

edit:
agh, wait, reread your post joey, so i dont have a confirmation if:

positive pin -- led -- gound pin

will work or if my math is correct and i need a:
positive pin -- 100-200ohm resistor -- led -- ground pin


lets just call them Circuit 1 and Circuit 2, which is the correct one?
