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.

This project utilizes OpenCV to capture live video and determine the HSV color of the center pixel. The detected color is then converted to RGB and transmitted to an Arduino, which controls an RGB LED ...

Connect the +ve end of the red led to pin 11 then connect the +ve end of the blue led to pin 10 then connect +ve end of the green led to pin 9. Take all the grounds common and connect to a 1k ohm ...

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. If you would prefer to build your very own ...

[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 ...

Anyone who has done anything with RGB LEDs knows that their ability to display pretty much any color is somehow both the best and worst thing about them. How do you get it right? How do you make your ...
