LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.
This is a very standard red LED. The lens is 3mm in diameter, and is diffused.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

What are the specs on this LED?
I had some red 3mm leds from radio shack and they were very dim next to these.
The ones from radio shack are 3mm red low intensity t-1 size 3v 15mA 2.5mcd
Do I need to add resistors to these LED's when connecting them in parallel to Lilypad?
