This is an Arduino RGB Colour Sensor breakout uses TAOS TCS3200 RGB sensor chip and 4 white LEDs. The TCS3200 arduino colour sensor can detect and measure a nearly limitless range of visible colours. Applications include test strip reading, sorting by colour, ambient light sensing and calibration, and colour matching, to name just a few. The TCS3200 has an array of photodetectors, each with either a red, green, or blue filter, or no filter (clear). The filters of each colour are distributed evenly throughout the array to eliminate location bias among the colours. Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen colour.
