Arduino Project 008 - RGB LED Mood Lamp

In the last project, you learned how to adjust the brightness of an LED using the PWM capabilities of the Atmega chip. You’ll now take advantage of this capability by using a red, green, and blue LED and mixing these colors to create any color you wish. From that, you’ll create a mood lamp similar to those seen in stores nowadays.
