This Arduino UNO project uses a joystick to control an RGB LED. When the joystick is at a certain position, the LED changes colors. An RGB LED is a type of LED that can reproduce almost any colour.

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying levels ...

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop ...

Like pretty much all of us, [Andy Schwarz] loves RGB LEDs. Specifically he likes to put them on RC vehicles, such as navigation lights on airplanes or flashers and headlights on cars. He found himself ...
