TCS3200 RGB Color Recognition Sensor Module

If you want to build a candy sorting machine or a robot that follows a specific colored line, this is the sensor you need. The central chip (TCS3200 or TCS230) has an array of microscopic photodiodes filtered for Red, Green, and Blue light. By reading the frequency output from the sensor, your Arduino can determine exactly what color is in front of it. The module includes four bright white LEDs to ensure the object is well-lit, preventing shadows from messing up the color reading.
