Adafruit FLORA Colour Sensor with White Illumination LED - TCS34725

Your electronics can now see in dazzling color with this lovely colour light sensor. Adafruit found the best colour sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the colour sensing photodiodes, minimizes the IR spectral component of the incoming light and allows colour measurements to be made accurately. The filter means you'll get much truer colour than most sensors, since humans don't see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass or fabric. To make sure you get consistent colour, Adafruit specified a nice neutral 4150?K temperature LED with a MOSFET driver onboard to illuminate what you're trying to sense. The LED can be easily turned on during sensing and turned off afterwards to save power. Connect to a Flora via I2C and the example code will quickly get you going with 4 channel readings. A detailed tutorial is in the works, till then, check out the Arduino library and follow the tutorial to install. Sew up the sensor by connecting 3V to 3V Flora output, Ground to common ground, SCL to I2C Clock and SDA to I2C Data on your Flora. All the pins line up and you can chain another sensor such as a lux sensor or accelerometer. Restart the IDE and select the example Flora sketch and start putting all your favorite fruit next to the sensor element!
