Code

/*
  DigitalReadSerial
 Reads a digital input on pin 2, prints the result to the serial monitor

 This example code is in the public domain.
 */

// digital pin 2 has a pushbutton attached to it. Give it a name:
int pushButton = 2;

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  // make the pushbutton's pin an input:
  pinMode(pushButton, INPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input pin:
  int buttonState = digitalRead(pushButton);
  // print out the state of the button:
  Serial.println(buttonState);
  delay(1);        // delay in between reads for stability
}


Code Indonesia

/*
 DigitalReadSerial
 Baca digital input di pin 2, print hasil ke serial monitor
 */

// digital pin 2 di sambungkan ke pushbutton
int pushButton = 2;
void setup() {
  // initialisasi serial communication pda 9600 bits per second:
  Serial.begin(9600);
  // set pushButton pin sebagai input
  pinMode(pushButton, INPUT);
}

void loop() {
  // baca input pin:
  int buttonState = digitalRead(pushButton);
  // print kondisi pushButton
  Serial.println(buttonState);
  delay(1);        // delay antar reads
}
