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.

[Rick] chose an Arduino to do all the heavy lifting for the light sensor and activating the LEDs. After a few tests [Rick] got his color sensor working, but it’s not up to par with what he had ...

Arduino enthusiasts may be interested in a new single pixel scanning camera which is powered by an Arduino Uno combined with a TCS34725 sensor available from online stores such as Adafruit.

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.

If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor.

You can actually build your own color-sensing lamp with this $8 Adafruit RGB color sensor, and follow along with plenty of Arduino tutorials online. But look how cool and sleek its product video is!

A tiny sensor may soon change the way your phone camera sees color — resulting in more accurate reproduction and skin tones. And it looks mighty impressive.

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

The Arduino-compatible lighting RGB LED lighting shield reviewed here was designed to give designers a low-cost easy-to-use open-source platform for fast prototyping and inexpensive evaluation of ...
