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.

At the heart of his unusual camera is the TCS34725 RGB color sensor from Adafruit ... and a 3mm OD aluminum tube. This allows an Arduino Uno to determine the color of this tiny slice of light ...

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. User interface for the handheld device is ...
