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

Code

// connect the sensors to digital pins
#define LEFT_SENSORPIN 4
#define CENTER_SENSORPIN 5
#define RIGHT_SENSORPIN 6
 
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);
}
