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
