How to interface Arduino with IR sensor(IR Obstacle Avoidance Sensor)
This video is for Educational Purposes!
Output is shown on Arduino serial monitor screen!

Source code:
int LED = 13; // Use the onboard Uno LED
int isObstaclePin = 2; // This is our input pin
int isObstacle = HIGH; // HIGH MEANS NO OBSTACLE
void setup() {
pinMode(LED, OUTPUT);
pinMode(isObstaclePin, INPUT);
Serial.begin(9600);
}
void loop() {
isObstacle = digitalRead(isObstaclePin);
if (isObstacle == LOW)
{
Serial.println("OBSTACLE!!, OBSTACLE!!");
digitalWrite(LED, HIGH);
}
else
{
Serial.println("clear");
digitalWrite(LED, LOW);
}
delay(200);
}
