How does a newb connect 2 LED's off an IPAC?

I've searched and searched.... I know I'm missing something easy, as this seems like a topic already discussed(but I couldn't find it). I don't mind doing some reading, but what I want to do is power 2 LED's off my ipac. I want to light up 2 of the 25cent buttons from Mike. I'm a total novice at this. I don't know much about resistors. Has anyone created a guide or can anyone send me to a website where I can read up on this(from a rookie's perspective).

Thanks.

good place to start if you want to use the led inputs from the ipac:

otherwise use an led resistor calculator and simply tap into the 5v:

Thanks... I read the pages. I guess what I'm having a problem with is the resistors. I'm not sure how they connect to the LED's. And I'm also not sure how they physically connect to the ipac. I would like a real rookie tutorial on how to hook up a couple LED's to the Ipac.

It sounds like I need to buy some LED's and put in a resistor that brings the 5v down to whatever the led actually needs. Am I close?

whammoed:

Yep, thats pretty much it.  I'm guessing you simply want the leds on all the time?
All you need to do is put the resistor inline with the power to the led.  Hook the +5volts to the resistor and the resistor to the longer leg of the led.  Hook the shorter leg of the led to ground.

Yes, always on. Ok. I think with the information you have given me and some trial and error I can figure the rest out.

Thanks Whammo!
