S6 Makerspace (Distance Alarm)

We did a Distance Sensor, that buzzes when anything is 15 cm close to the Distance Sensor, the use of our project is when you need privacy on your room, when someone enter your room, the buzzer is going to Buzz.

Coding:

int duration:

int distance:

int const trigPin = 9;

int const echoPin = 10;

int buzzer = 2;

void setup( ){

pinMode(trigPin , OUTPUT);

pinMode( echoPin , INPUT);

pinMode( buzzer , OUTPUT);

}

void loop( ){ digitalWrite(trigPin, HIGH); delay(2);

digitalWrite(trigPin, LOW);

duration = pulseIn (echoPin , HIGH);

distance = (duration * 0.034)/2; if(distance < 15){ digitalWrite(2, HIGH);

}

else{ digitalWrite(2, LOW);

}

}
