Introduction
You know what’s even more fun than a blinking LED? Changing colours with one LED. RGB, or red-green-blue, LEDs have three different color-emitting 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!
Parts Needed
You will need the following parts:
- 1x Breadboard
- 1x RedBoard or Arduino Uno
- 1x LED - RGB Common Cathode
- 3x 330Ω Resistors
- 5x Jumper Wires
