    Security systems have detection algorithms in several ways.This project will do our Security System With Arduino with sensors are sensitive to movement.When the system detects motion alarm will alert us by entering circuit.

    Materials:

    • Arduino
    • PIR Motion Sensor
    • Buzzer (Buzzer active in the project used)
    • Led

    Electronic circuit diagram:

    Arduino Software:

    //Software development by Robimek
    // Software license by Robimek
    int inputPin = 2;
    int pirState = LOW;
    int val = 0;
    int buzzerpin = 10;
    int led = 13;
    void setup() {
    pinMode(inputPin, INPUT);
    pinMode(buzzerpin, OUTPUT);
    pinMode(led, OUTPUT);
    Serial.begin(19200);
    }
    
    void loop(){
    val = digitalRead(inputPin);
    if (val == HIGH) {
    beep(500);
    digitalWrite(led, HIGH);
    delay(500);
    
    if (pirState == LOW) {
    
    Serial.println("Hareket Algilandi!");
    
    pirState = HIGH;
    }
    } else {
    digitalWrite(buzzerpin, HIGH);
    digitalWrite(led, LOW);
    delay(150);
    if (pirState == HIGH){
    Serial.println("Hareket Algilanmadi!");
    
    pirState = LOW;
    }
    }
    }
    void beep(unsigned char delayms){
    analogWrite(10, 255);
    delay(delayms);
    analogWrite(10, 150);
    delay(delayms);
    
    }

     

    We’re doing all the wiring and installing our software.We have completed our alarm system.

    Note: Project actively used for buzzer while passive ‘HIGH’ case, while active ‘LOW’ What happens in case.You are the exact opposite to be passive buzzer, the software in the ‘HIGH’ and ‘LOW’ to change the situation.
