For prototyping, Infineon has a RGB LED lighting control shield for Arduino, based around its ARM Cortex-M0 XMC1202 microcontroller. On board is something called a ‘brightness colour control unit’ ...

This was controlled with an Arduino Uno. The LED matrix was mounted inside the shadow box, behind the vellum paper. The Arduino code was easily written using Adafruit’s RGB Matrix Panel library.

Each addressable LED has an integrated driver that allows you to control the color and brightness of each LED independently. The combined LED/driver chip on the LED is the extremely compact WS2812B – ...

Now, though, it shouldn’t be hard to control the RGB LED strips through an Arduino, a computer, or even an Android/iOS device with a small IR LED plugged into the headphone jack.

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

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.

BIOSTAR introduces a scheme to help users streamline motherboard and chassis RGB lighting.
