Why put a resistor on the LED...you want almost no resistance on the
circuit.

Thank you Bernd!! :)
I should go with a red LED,because it won't need as
much current,but I like BLUE! If I feed it through a
1kohm resistor or higher,it should be a negligible
draw,not enough to affect anything.
Thanks!
