COMPONENTS REQUIRED:-

Arduino Board X 1

IR Sensors X 1

LED X 1

Theory-

Arduino interfacing with IR Proximity sensor is very simple like interfacing of Switch with the Arduino, The obstacle sensor gives logic 0 as output when there is no obstacle in front of it, and when obstacle is placed in front of it, it will give logic high output i.e. +5V. We need to read these logic changes on the Arduino. Using digitalRead Command. In my design I have connected its output to Pin 2 of Arduino You can use any other IO line as per your requirement.

CODE-

const int ProxSensor=2;

void setup()

{

pinMode(13, OUTPUT);

pinMode(ProxSensor,INPUT);

}

void loop()

{

if (digitalRead(ProxSensor)==HIGH)

{

digitalWrite(13, HIGH);

}

else

digitalWrite(13, LOW);

delay(100);

}
