Led Question
« on: January 10, 2008, 12:48:59 PM »
I dont have any experience with making a led circuit. (yes, i'm a nub) So i wanna be sure how to do it properly.
I want to have 2 blue leds for the umd jewel, and i know a parellel circuit is needed.
But i'm not sure if i use 4 wires or 2 wires. And i believe a resistor is not neccessary for blue leds?
So which one do i have to use?

wait, doesn't that mean you will have strip the wire in the middle?

*EDIT*
Does it have to be 2 wires? Or can you use 4 wires:

---------------------------
                         ||||||                                       ||||||
                         ----------------------------------------------
                         Sideways look       ||| being leds --- being wire

What i mean is that, can you solder a wire on the top and on the bottom of the led?

No you have to solder on the + and - of the led, theres no point soldering on the top and bottom?
