void setup(){

  //start serial connection

  Serial.begin(9600);

  //configure pin2 as an input and enable the internal pull-up resistor

  pinMode(2, INPUT_PULLUP);

  pinMode(3, INPUT_PULLUP);

  pinMode(13, OUTPUT); 

}

void loop(){

  //read the pushbutton value into a variable

  int sensorVal = digitalRead(2);

  int sensorVal3 = digitalRead(3);

  if (sensorVal == LOW)Serial.print('0');

  if (sensorVal3 == LOW)Serial.print('1');
