SIRINE ARDUINO

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);
  }
}
