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.

[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 lev… ...

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 ...

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 ...
