3 channel tracking sensor example

This Tracking Sensor for Arduino can detect the white lines in black and black lines in white. This particular module has 3 sensors

Using infrared light detection, anti-interference ability
Built-in LED indicator lights
Sensor CTRT5000, high sensitivity, stable performance
Operating voltage 5V, output low black line, white line output high

This module worked with 3.3v as well in my basic tests

Connection

Code

[codesyntax lang=”cpp”]

// connect the sensors to digital pins
#define LEFT_SENSORPIN D6
#define CENTER_SENSORPIN D7
#define RIGHT_SENSORPIN D8

void setup()
{
  Serial.begin(9600);
  pinMode(LEFT_SENSORPIN,INPUT);
  pinMode(CENTER_SENSORPIN,INPUT);
  pinMode(RIGHT_SENSORPIN,INPUT);
}

void loop()
{
  // read input from sensors
  byte leftSensor=digitalRead(LEFT_SENSORPIN);
  byte centerSensor=digitalRead(CENTER_SENSORPIN);
  byte rightSensor=digitalRead(RIGHT_SENSORPIN);

  Serial.print(" Left : ");
  Serial.print(leftSensor);
  Serial.print(" Centre : ");
  Serial.print(centerSensor);
  Serial.print(" Right : ");
  Serial.print(rightSensor);
  Serial.println();
  delay(1000);
}
