[Jose] has been featured here before for his innovative Arduino-driven RGB lighting projects, and this is another great project which builds on that theme!

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino.

Description: In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever ...

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 ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show ...

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.
