Make your Hello world! LED project a little more jazzy with these rainbow LEDs. All you have to do is to provide power, and they'll cycle through all the colours of the rainbow!
These 5mm LEDs look (from the outside) and work just like single colour LEDs, except that they cycle through every hue at three different speeds (fast, medium, slow) one after the other.
