You know what’s even more fun than a blinking
LED? Changing colors with one LED. RGB, or
red-green-blue, LEDs have three dierent color-emit-
ting diodes that can be combined to create all sorts of
colors. In this circuit, you’ll learn how to use an RGB
LED to create unique color combinations.
Depending on how bright each diode is, nearly any
color is possible!
