Punctuation Method :: Arduino code

int analogOne = 0;       // analog input 
int analogTwo = 1;       // analog input 
int digitalOne = 2;      // digital input 

int sensorValue = 0;     // reading from the sensor

void setup() {
  // configure the serial connection:
  Serial.begin(9600);
  // configure the digital input:
  pinMode(digitalOne, INPUT);
}

void loop() {
  // read the sensor:
  sensorValue = analogRead(analogOne);
  // print the results:
  Serial.print(sensorValue, DEC);
  Serial.print(",");

  // read the sensor:
  sensorValue = analogRead(analogTwo);
  // print the results:
  Serial.print(sensorValue, DEC);
  Serial.print(",");

  // read the sensor:
  sensorValue = digitalRead(digitalOne);
  // print the last sensor value with a println() so that
  // each set of four readings prints on a line by itself:
  Serial.println(sensorValue, DEC);
}
