2. Alat dan Bahan:

- Arduino Uno 1 buah

- Kabel Jumper

- Lampu LED 8 Watt

- Relay 1 buah

- Baterai 9 volt

- Stop Kontak

3. Berikut adalah kode program yang di uploud ke arduino IDE:

// Clap Light Switch

int mic = 2;       // microphone module

int indicLED = 13; // indication pin

int lightPin = 9;  // relay (lights control)

bool lightState = true;

bool ignoreInt = false;

bool ClapDetected = false;

uint32_t ClapDetetedTime [3] {};

void setup() {

  Serial.begin(115200);

  pinMode(indicLED, OUTPUT);    

  pinMode(lightPin, OUTPUT);  

  digitalWrite(lightPin, lightState);

  attachInterrupt(digitalPinToInterrupt(mic), ISR_ClapDetected, FALLING);

}

void loop() {

delay(2);

if(millis() - ClapDetetedTime[2] >= 800)

{

  digitalWrite(indicLED, LOW);

}

if(millis() - ClapDetetedTime[2] < 800 && millis() - ClapDetetedTime[1] < 800 && ClapDetected && ClapDetetedTime[1] - ClapDetetedTime[0]>=800)

  {

    Serial.println("double clap detected");

    digitalWrite(indicLED, LOW);

    Serial.print("Setting light to ");

    Serial.println(String(!lightState));

    digitalWrite(lightPin, lightState);

    lightState=!lightState;

    ClapDetected = false;

  }

}

void ISR_ClapDetected()

{

  if(millis() - ClapDetetedTime[2] > 200){ // debounce

  for (int i = 0; i != 2; i++) {

  ClapDetetedTime[i] = ClapDetetedTime[i + 1];

  }

  ClapDetetedTime[2] = millis();

  ClapDetected = true;

  Serial.println("clap detected");

  digitalWrite(indicLED, HIGH);

  }

}
