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
