Or Copy Code Given Below :-
int irSensor = 2; // IR sensor OUT pin
int led = 13; // LED pin
void setup() {
pinMode(irSensor, INPUT);
pinMode(led, OUTPUT);
Serial.begin(9600);
}
void loop() {
int sensorValue = digitalRead(irSensor);
if (sensorValue == LOW) { // Object detected
digitalWrite(led, HIGH);
Serial.println("Object Detected!");
} else { // No object
digitalWrite(led, LOW);
Serial.println("No Object");
}
delay(200);
}
