Introduction
This short video demonstrates how to connect a common anode Piranha RGB LED to an Arduino and to drive each of the red, green and blue channels individually using PWM (Pulse Width Modulation). A 4×20 LCD Module is connected to the Arduino and the red, green and blue channels are displayed on it. It could be use to create a “mood light”. I will use the Arduino to drive the common anode RGB LED, using PWM to give us all of the possible colours. It’s a bright LED that works very well.
