#3IR sensor with Arduino | amazing mj

In this #3rd arduino series tutorial i am going to show you how to interface IR sensor with Arduino.

What is IR proximity sensor? 

>This IR Proximity Sensor is a multipurpose infrared sensor which can be used for obstacle sensing, color detection, fire detection, line sensing, etc and also as an encoder sensor. The sensor provides a digital output.

In this project we use obstacle sensing IR sensor. Which give high digital output (which means "1" ) when any obstacle detected.

What we need ?

>Arduino 

>IR sensor

>LED

>220ohm resistor 

>bread board (not mandatory)

>some wires

//this code is for turn on led with IR sensor 
/**************************code******************************/

int state=0;
void setup() {
pinMode(3,INPUT);
pinMode(13,OUTPUT);
}

void loop() {
  state=(digitalRead(3));
  if(state==0)
  {
    digitalWrite(13,HIGH);
  }
  else
  {
    digitalWrite(13,LOW);
  }
}
