BLUE4 to a 100 ohm resistor to pot pin 17 To ground the LED busses, we’ll be using four 2N2222 transistors. The Arduino will trigger each transistor individually through a 1Kohm resistor.

Off the shelf RGB colour pickers allowing you to extract and objects RGB values can range from a few hundred dollars to thousands depending on your needs.

The Arduino-compatible lighting RGB LED lighting shield reviewed here was designed to give designers a low-cost easy-to-use open-source platform for fast prototyping and inexpensive evaluation of ...

RGB LED Strip ($15.95): This is the core of our project. This strip of lights will light up with the same color as your computer screen and make it seem like the screen is bigger than it really is.
