First Timer LED/Resistor question

[EvanW]

Hi All,

I am about to try my first lighting project. I was wondering if anyone can tell me if the resistor gets soldered to a (long) or k (short) end of the led. The resistors were so cheap that I'm going to solder one to each led.

Thanks,

Evan

The resistor should go to the short (negative) side. Here is a site that may be helpful if you are using multiple LEDs.

Here is a great site with a super variety of LEDs in different colors and viewing angles (they are cheap too):

LEDs are pretty easy to work with and fun, lol. Good luck!

It doesn't really matter what lead it's on as long as they're in series. The resistor should limit the current no matter what side of the diode it's on.

See Kirchhoff's Current Law for more information.

True but it's a good habit to keep them consistant. It avoids problems :lol

I ordered up a bunch to try them out.

Ebay is the way to go.
I don't know how they can sell them so cheap.
