Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino.

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’ ...

It’s really just an Arduino, RGB LED matrix, and a programmed particle system, but if we’re fascinated by it, it will probably blow an infant’s mind.

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.
