ARDUINO WITH IR SENSOR

In this tutorial you will get to know that how you can create an Infrared detection system .

Material requirements are given below :-

• IR SENSOR
• ARDUINO
• GREEN LED
• RED LED
• BRAEDBOARD
• JUMPER WIRES

Whenever any object comes in front of IR sensor red starts glowing otherwise green led glows indicating no object in front.

The range of sensor can be changed by changing the direction of regulator present on sensor.

CONNECTIONS

ARDUINO

GND          =     -ve of green , red LED and

                          GND of IRsensor

5V              =     VCC of IR sensor

2                =      +ve of red LED

3                =      +ve of green LED 

4                =      OUT of IR sensor

CODE OF THE PROJECT :-

const int IR = 4;
const int green = 3;
const int red = 2;

void setup() {
pinMode(IR, INPUT);
pinMode(green, OUTPUT);
pinMode(red, OUTPUT);
}

void loop() {
if(digitalRead(IR) == HIGH){
  digitalWrite(green,LOW);
  digitalWrite(red,HIGH);

}

else{
  digitalWrite(green,HIGH);
  digitalWrite(red,LOW);
 
}
}
