TCS230/TCS3200 Color Sensor with Arduino

Introduction

This guide shows you how to use the TCS3200 Color Sensor with Arduino. The TCS3200 can be used to detect the colour of an object. It can also be used to measure the intensity of light.

The TCS3200 color sensor is a fast, easy-to-use, and low-cost color sensor that can be used with an Arduino. The sensor has a built-in red, green, and blue (RGB) LED that can be used to test the color of an object. The sensor can also be used to measure the intensity of light.

What is the TCS230 Color Sensor?

Color Sensor With Arduino

The TCS230 Color Sensor is a light-to-digital converter that uses a photodiode to sense the intensity of light. The output of the sensor is proportional to the intensity of the light. The sensor has a three-colour LED that is used to illuminate the object being measured. The LED emits red, green, and blue light, and the photodiode measures the intensity of the light. The output of the sensor is a digital signal that is sent to a microcontroller. The microcontroller can be used to calculate the colour of the object being measured. How Color Sensors Work

One of the most significant factors for the development of a project is the identification of the pins of our module, therefore, below is a full image of the sensor with the TCS230 Chip in the centre and its respective extensions for installation pins.

The TCS230 color sensor has two rows of 5 pins, where we find the control pins ( S0 , S1 , S2 , S3 ), output ( OUT ), LED control ( LED ) and power ( VCC and GND ). The Vcc and GND pins are repeated, and you can use either of them to power the module.

Pins S0 and S1 determine the output frequency, and pins S2 and S3 choose which color level will be detected at the moment, according to the table below

S2 S3 Photodiode type
LOW LOW Red
LOW HIGH Blue
HIGH LOW Clear (No filter)
HIGH HIGH Green

The TCS230 chip is a programmable light-to-frequency converter with a square-cond output and a 50% Duty Cycle whose frequency is proportional to light intensity.

Features and Specifications

  • Input voltage: (2.7V to 5.5V)
  • Interface: Digital TTL
  • High-resolution transformation of light intensity to frequency
  • Programmable colour and full-scale output frequency
  • No need for ADC(Which can be directly connected to the digital pins of the microcontroller)

How to use the TCS230 Color Sensor with Arduino?

In our circuit, we are going to use an Arduino Uno, a TCS3200 color sensor and a RGB LED , which will light up in red, green or blue depending on the color of the object placed in front of the sensor:

Conclusion

After uploading the code in Arduino ide As you can see, the RGB LED will light up according to the colour of the object in front of the sensor, be it blue, green or red.

Conclusion

When recognising the blue colour, the claw closes in order to capture the object in front of it, and otherwise, the claw will remain open, as if waiting for a new reading.
