Yes, every LED gets its own resistor and you can connect as many as you want that way.
Thank you.Great tutorial.
Forgive me for a possible silly question, but why are the resistors on the negative side of the LEDs? I've never seen that done before and always thought they need to be on the positive side to limit the current before it goes through the LED, or does this not matter?
Glad to hear it!
I guess I should offer this:
I have both 5mm and 3mm White and Red LEDs - the very bright kind (don't ask how many mCd they are, I don't know). I also have the resistors for the LEDs to run at 6 volts as per my tutorial.
$1 for a pair of LEDs complete with a pair of resistors. Shipping is extra.
Make use of the old servo cable.
