KY-033 Line Tracking Sensor Using Arduino

on

Line Tracking Sensor KY-033  with Arduino and Buzzer:

In this example, we will connect the line tracking sensor KY-033 with the Arduino to control a buzzer.

Component Required:

  • Line tracking sensor KY-033
  • Arduino UNO
  • 5V buzzer
  • 2 LEDs
  • 2 Resistors 220 ohm

KY-033 Arduino Circuit connection:






KY-033 Line Tracking Sensor Arduino Code:

#define sensor 2
#define buzzer 3
#define red 4
#define green 5

void setup() {
Serial.begin(9600);
pinMode(sensor,INPUT);
pinMode(buzzer,OUTPUT);
pinMode(green,OUTPUT);
pinMode(red,OUTPUT);


}

void loop() {
bool value = digitalRead(sensor);
if(value == 0)
{
  digitalWrite(buzzer, HIGH);
    digitalWrite(green, HIGH);
      digitalWrite(red, HIGH);

}
else
{
    digitalWrite(buzzer, LOW);
    digitalWrite(green, LOW);
      digitalWrite(red, LOW);
  }
}

Real-World Applications:

Line trackers are sensors that help robots detect and follow a line. They are useful for navigation, allowing robots to autonomously move around a predetermined path. Line trackers are commonly used in industrial robots and autonomous vehicles. The line following robots is commonly used for carry children through shopping malls, homes, entertainment places, industries.
