Arduino Uno with Color Sensor Module (TCS3200): Unlocking the World of Colors



, ,


The Arduino Uno, in conjunction with the TCS3200 Color Sensor Module, empowers you to explore the fascinating realm of color detection and analysis. This comprehensive guide will walk you through the intricacies of the TCS3200 sensor, how it functions, and how to seamlessly integrate it with your Arduino Uno to create color-sensing projects.


The TCS3200 Color Sensor Module operates on the principles of colorimetry, which involves the measurement of color properties. It employs an array of photodiodes and color filters to detect the intensity of red, green, blue, and clear (no filter) light. By measuring the intensity of each color component, it can determine the overall color of an object placed in front of it.

Components Required

To embark on your color-sensing journey, gather the following components:

  1. Arduino Uno
  2. TCS3200 Color Sensor Module
  3. Breadboard
  4. Jumper Wires
  5. White sheet or surface for color calibration (optional)


Connect the TCS3200 Color Sensor Module to the Arduino Uno as follows:

  1. VCC of the module to 5V on the Arduino.
  2. GND of the module to any ground (GND) pin on the Arduino.
  3. S0, S1, S2, and S3 of the module to digital pins on the Arduino (e.g., D2, D3, D4, and D5).
  4. OUT of the module to any digital pin on the Arduino (e.g., D6).
  5. OE (Output Enable) of the module to ground (GND) on the Arduino.


Here’s a basic Arduino code example to read and display the detected color:

#include <Adafruit_TCS3200.h>

Adafruit_TCS3200 colorSensor;

void setup() {




void loop() {;

  uint16_t red =;

  uint16_t green =;

  uint16_t blue =;

  uint16_t clear = colorSensor.clear();

  Serial.print("Red: "); Serial.print(red);

  Serial.print(" Green: "); Serial.print(green);

  Serial.print(" Blue: "); Serial.print(blue);

  Serial.print(" Clear: "); Serial.println(clear);




The Arduino Uno paired with the TCS3200 Color Sensor Module opens up a world of possibilities for color detection and analysis. Whether you’re building a color sorting machine, a color-based game, or simply exploring the fascinating world of colors, this combination provides a versatile platform for your creative projects.


  1. Can I use the TCS3200 Color Sensor Module for distinguishing specific colors or shades?
  • Yes, you can distinguish specific colors or shades by calibrating the sensor against known color samples. By comparing the sensor’s readings to a color reference, you can create a color recognition system.
  1. What is the maximum range for color detection with the TCS3200 module?
  • The range for color detection depends on factors like lighting conditions and the color of the object being sensed. Generally, the sensor can reliably detect colors within a few centimeters of the object.

Troubleshooting Q&A

  1. I’m getting inconsistent color readings. What could be causing this issue?
  • Inconsistent readings may result from varying lighting conditions or improper calibration. Ensure consistent and adequate lighting for accurate results. Additionally, calibrate the sensor to white under your specific lighting conditions.
  1. How can I calibrate the TCS3200 Color Sensor Module for accurate color detection?
  • Calibrating the sensor involves placing it in front of a known white surface and adjusting the S2 and S3 pins to set the scaling factor. This step helps standardize the sensor’s response to different lighting conditions.

By following this guide, you’ll unlock the potential of the TCS3200 Color Sensor Module in conjunction with the Arduino Uno. Whether you’re pursuing creative color-based projects or practical color analysis applications, this combination provides a versatile and reliable solution for your needs.
