SIRINE ARDUINO

Berikut saya akan simulasikan sirine menggunakan mikrokontroller arduino. perhatikan langkah kerja berikut ini seperti biasa

1. Gambar kerja/sketsa
2. Buat Diagram alir
3. Buat sketsa/koding/program
4. verifikasi pada aplikasi arduino/compiled
5. Upload

Kebutuhan :

1. Buzzer :

   

2. NTC Temperatur

   

3. Arduino UNO dan LED

   

SKETSA RANGKAIAN :

KODING :

/**

int INTO = 2;

int INTO = 0;

int LED1 = 3;

int LED2 = 4;

int spk = 5;

*/

void setup() {

  pinMode(2, INPUT);

  pinMode(3, INPUT);

  pinMode(4, INPUT);

  pinMode(5, INPUT);

}

void loop() {

  if (digitalRead(2) == LOW) {

    tone(5, 900);

    delay(500);

    digitalWrite(3, HIGH);

    digitalWrite(4, LOW);

    digitalWrite(5, HIGH);

    delay(1);

    tone(5, 800);

    delay(500);

    digitalWrite(3, LOW);

    digitalWrite(4, HIGH);

    delay(100);

  }

 

  else {

    digitalWrite(3, LOW);

    digitalWrite(4, HIGH);

    digitalWrite(5, LOW);

    delay(100);

    digitalWrite(3, HIGH);

    digitalWrite(4, LOW);

    digitalWrite(5, HIGH);

    delay(100);

  }

}
