Wire up the sensor by connecting VDD to 3-5VDC, Ground to common ground, SCL to I2C Clock and SDA to I2C Data on your Arduino.
We include some example code to detect light lux and temperature that we snagged from the eval board software. In addition to a processor and a color sensor, you will need an RGB LED. The LED can be easily turned on or off by any logic level output.Ĭonnect to any microcontroller with I2C and our example code will quickly get you going with 4 channel readings. Arduino library for interfacing to the fingerprint sensor in the Adafruit shop. Finally, we specified a nice neutral 4150°K temperature LED with a MOSFET driver onboard to illuminate what you're trying to sense. We add supporting circuitry as well, such as a 3.3V regulator so you can power the breakout with 3-5VDC safely and level shifting for the I2C pins so they can be used with 3.3V or 5V logic. First wire up a TCS34725 to your board exactly as shown on the previous pages for Arduino.
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. The filter means you'll get much truer color than most sensors, since humans don't see IR. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The TCS34725, which has RGB and Clear light sensing elements. Components Needed To Build Arduino And TCS34725 RGB Color Sensor Project Hardware Components.
