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 is a tiny and clearly arranged Arduino library for the basic RGB LED functions, to easily drive an RGB color LED (common anode/common cathode) and mix the colors. It uses the principle of ...

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 ...

[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 ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...

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 ...

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller ...
