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 ...

A library that provides many different ways to control an RGB LED connected to an Arduino. My first attempt at object oriented programming on the Arduino. Easiest way to use the library is to download ...

the RGB LED color mixer is a project that is suitable for the beginner Arduino users who is interested in building an interactive gadget to mix colors. The simple circuit combines three potentiometers ...

The circuit diagram shows the connection between all the electronic components and Arduino Nano. Also check various NeoPixel LED based projects by following the link.

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 ...

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 ...
