I found some LEDs that I have been using with my nerdkit, but I don't have the specs for these. I am wanting to hook some of these LEDs up for a project using 2 AA batteries, but I'm not sure what resistor to use. I was thinking I could limit the AAs to the same voltage and current output as the nerdkit.

I would measure these, but I don't have a working multimeter at this time.

Thanks Shawn.

Hi Shawn,

The exact specs of the LEDs we use in our NerdKits change a bit every so often (mostly when vendors run out of a certain type). But for the most part we try to keep them pretty consistent, there is a thread here about the LEDs from which I linked to the datasheets.

Thank you very much. That is what I was needing.
