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.

John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller. (Click the links to see PDFs of the complete ...

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.

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.

Two new development kits that require Arduino programming skills could make it easier for the do-it-yourself set to build electronics and wearable devices.
