Im planning on adding some LEDs and I was wondering what voltage they run at, and how to hook them up.

Most I've encountered run from 2.1-3.6v., but there is a lot of variety.

Here's a couple of guides to help you out;

Voltage depends on the LED. Red ones usually run on 1.5-2V, blue ones as much as 6V.
