#4 Sensor Suara

Sensor suara menggunakan mic

Kode Program 1: pembacaan data sensor digital

volatile boolean data_;volatile boolean a;
void setup(){  Serial.begin(9600);  data_ = 0;  a = 0;  pinMode(22, INPUT);}
void loop(){  if (data_ == digitalRead(22)) {    data_ = digitalRead(22);    a = !a;    Serial.print("sensor:");    Serial.println(a);    delay(100);
  }}

Kode Program 2: pembacaan data sensor analog

int a; //membuat variabel "a"void setup(){ Serial.begin(9600); a = 0; //diawal program, variabel a di isi nilai nol}void loop(){ a=analogRead(34) //data diisi pembacaan sensor Serial.print("sensor:"); //mencetak teks "Sensor=" ke seial monitor Serial.println(a); //mencetak nilai a ke seial monitor delay(100);}
