Title: RESISTORS help!!
Post by: knightimer on August 26, 2007, 06:21:23 AM

HELP! i cant find a 340 ohm resistor!!! !!! !! only 330ohm!!! and 390ohm!!! i think its cuz i live in Australia! !!! !! HELP! wait the question...would the 330ohm work on yur $50 robot tutorial?!!!! if not, how bout 390ohm??!!

help help help

Man does your life depend on this robot? It sure sounds like it...
And it's not because you live in australia. It's called the E12 series of resistors.
Google is your friend.

anyway, just put a 330 resistor in series with a 10 ohm...

Im sure that a 330 ohm resistor by itself will do. These resistor values are rarely very precise anyway. For powering a LED anything between 200 and 500 will do i should think.

I didn't pay attention to what the resistor would serve for, and indeed,
if it's only for a LED there is really no problem at all.

330 ohm should do. If you really want 340 measure a couple of 330 and probably you will find that some have resistance around 340 ohm.

This topic should be in Electronics area i think?
