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 ...

Thanks to a simple computer vision program in python, we can control the RGB LED light color moving our index and thumb. The RGB LED color will change based on the distance between index and thumb ...

A Tech Enthusiast has shared his new open-source project, the 9x9x9 LED Cube, which takes 3D visualization to the next level with its modular design and interactive features. This cube consists of 729 ...

[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 ...

Welcome to my tutorial on building what might be the world’s smallest RGB LED Cube! In this project, I’ll walk you through the entire process of designing and assembling an ultra-compact LED cube, ...

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 ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...
