Getting started with PIR Sensor and Arduino

 

Hi everyone,

I am vigneshraja. Here I presented the code for interfacing arduino UNO with PIR Motion Sensor like shown in above video.

Code:

const int PIRPin = 2;

const int LEDPin = 13;

int PIRState = 0;

void setup() {

  pinMode(PIRPin,INPUT);

  pinMode(LEDPin,OUTPUT);

  Serial.begin(9600);

}

void loop() {

  PIRState = digitalRead(PIRPin);

  if(PIRState == HIGH)

  {

    digitalWrite(LEDPin,HIGH);

    Serial.println("Motion detected!");

  }else

  {

    digitalWrite(LEDPin,LOW);

  }

}

Thank you for reading
