We’ve seen similar projects, but we are always struck how simple this sensor is to use. Combine these with an RGB LED and you can make a chameleon.

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.

Get the right color every time. Now through 11:59 pm PT on 5/31, you can get the Nix Mini 2 Color-Matching Sensor for half off $99 at just $49.97.

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.

Through May 31, you can get the Nix Mini Color-Matching Sensor V2 for just $49.97 (reg. $99) in honor of Memorial Day.
