Security alarm system with arduino | Laser sensor project

Thanks for Visiting here

Laser sensor Project😋

in this Project we will make very useful project which is security alarm system this project is widely use for secure any expensive item like jewelry and so on.

Laser sensor project 

How this project work :

if we  look this project works then we obserb that it is two parts first is laser and second part is Laser sensor(which is sens laser light is coming or not) after sens laser ray laser sensor gives some data like high or low then we can use this data any perform various type of command by arduino board

Before starting to make this project first look of project;

I hope you like this project if you like please mention in comment section I like this project

 Last start:

Components required 

1. arduino board

2. Laser 

3. Laser sensor

4. Buzzer

Last move to the Wiring part

Laser Wiring

Laser	ARDUINO
-	GND
+5v	+5v
s	3

Laser sensor wiring

Laser Sensor	Arduino
GND	GND
+5v	+5v
s	2

Buzzer Wiring

GND-GND

POWER-4

After completing Wiring Do coding 

int LaserSensor = 2;

int SensorReading = HIGH;  // HIGH MEANS NO OBSTACLE

int Laser = 3;

int buzz = 4;

 

void setup() {

  Serial.begin(9600);

  pinMode(Laser, OUTPUT);

  pinMode(LaserSensor, INPUT);

  pinMode(buzz,OUTPUT);

}

void loop() {

  digitalWrite(Laser, HIGH);

  delay(200);

  SensorReading = digitalRead(LaserSensor);

  if (SensorReading == LOW)

  {

  digitalWrite(buzz,LOW);

  }

 

  else

  {

     digitalWrite(buzz,HIGH);

  }

}
