Getting Started with Arduino and IR Obstacle Sensor

Hi everyone,

I am vigneshraja. here I presented the code for interfacing arduino UNO with IR Obstacle Sensor like shown in above video.

Code:

const int sensorPin = 2;    

const int ledPin =  13; 

int sensorState = 0; 

void setup() {

  Serial.begin(9600);

  pinMode(ledPin, OUTPUT);

  pinMode(sensorPin, INPUT);

}

void loop() {

  sensorState = digitalRead(sensorPin);

  Serial.println(sensorState);

  if (sensorState == HIGH) {

    // turn LED on:

    digitalWrite(ledPin, LOW);

  } else {

    // turn LED off:

    digitalWrite(ledPin, HIGH);

  }

}

Thank you for reading
