Colour Identification Using TCS3200 Module

The Colour Identification Using TCS3200 Module project relies on an Arduino Uno board to orchestrate light sensing and data display. At the heart of the sensing mechanism is the TCS3200 colour sensor module, which uses an array of photodiode detectors coupled with current-to-frequency converters. When pointed at an object, the sensor measures the intensity of red, green, and blue light reflected from the surface by filtering the light through specific internal colour filters configured via control pins. The sensor emits a square wave output signal whose frequency is directly proportional to the light intensity of the active colour channel. The Arduino Uno board captures these frequency pulses and processes the incoming data to calculate chromaticity coordinates. By comparing these relative ratios of red, green, and blue values, the microcontroller determines the dominant colour. Once the colour is identified, the Arduino formats the corresponding text string and transmits it to a 16x2 LCD screen, which visually updates to display the detected colour name to the user in real time.
