Accident Prevention System Using Eye Blink Sensor

Circuit Diagram

Code

int sensor = 8;

int buzzer = 11;

int motor = 6;

void setup()

{

 

  pinMode(buzzer, OUTPUT);

  pinMode(sensor,INPUT);

  pinMode(motor,OUTPUT);

  digitalWrite(motor,HIGH);

}

// the loop function runs over and over again forever

void loop() {

  if(digitalRead(sensor)==1)

  {

    digitalWrite(11,LOW);

    digitalWrite(motor,HIGH);

  }

  else

  {

    delay(3000);

    digitalWrite(11,HIGH);

    digitalWrite(motor,LOW);

  }

  

}
