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.

It displays the color and lights up an LED to correspond to the detected color. If you haven’t seen the TCS230 before, it is a chip with an array of photosensors, for different light wavelengths.

Description: In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever ...

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.

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 ...
