Tutorial: How to use Color Sensor Module TCS-34725

The TCS-34725 color sensor module is a useful component for makers who want to measure and analyze ambient color. It is ideal for projects such as weather monitoring, color-based interactions, or artistic applications.

What you need

• Arduino Uno
• USB A-Micro B cable
• Connect to PC

Steps

1. Connect the following pins of the TCS-34725 module to the Arduino: SDA to pin 20, SCL to pin 21, GND to ground and VCC to power supply voltage.
2. Install the Adafruit_TCS34725 library via Arduino Library Manager or by downloading the source code from the official repository.
3. Check the module’s datasheet to ensure that all settings and connections are correct.
4. Write a simple sketch using the installed library to read RGB values from the sensor.
5. Upload the sketch to Arduino via the USB cable.
6. Open the Serial Monitor in Arduino IDE at 9600 baud and view the color data received from the module.

Example code

//Includi la libreria
#include <Adafruit_TCS34725.h>
//Instanzia l'oggetto sensore
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_700MS, TCS34725_GAIN_1X);
void setup() {
tcs.begin();
}
void loop() {
uint16_t r, g, b;
tcs.getRawData(&r, &g, &b); Serial.print("RGB: "); Serial.print(r); Serial.print(", "); Serial.print(g); Serial.print(", "); Serial.println(b);
}
