Component Introduction
A RGB LED also known as Tri-color LED consists of three LEDs with a red,
a green and a blue light. These three colored LEDs are capable of
producing any color. It uses a four-wire connection with one common
lead (anode or cathode). These LEDs can have either common anode or
common cathode leads.
Common Anode
RGB LED
What we used in this experiment is the common anode RGB LED. The longest pin is the
common anode of three LEDs. The pin is connected to the +5V pin from the Arduino, and the
three remaining pins are connected to the Arduino's D9, D10, D11 pins through a current
limiting resistor.
In this way, we can control the color of RGB LED by 3-channels PWM signal.
