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 Osgood] wanted to build a color sensor that could be held up to any object to get RGB color values. He originally started with a photoresistor and a few LEDs, but couldn’t get that to w… ...

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.

The Arduino Plug and Make Kit provides a 10-minute, cloud-based IoT solution that includes QWIIC and smartphone-based sensors, transducers, and actuators.

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 ...

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.

If you are just learning how to do Arduino projects or want to start, here are six fun and easy projects you can try that are perfect for beginner programmers.

For accurate humidity detection, colorimetric sensors must cover a wide range of colors, demonstrate a linear correlation between color and humidity, respond quickly, and maintain long-term stability.

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 ...
