/*
  AnalogReadSerial

  Reads an analog input on pin 0, prints the result to the Serial Monitor.
  Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

  This example code is in the public domain.

  The original sketch 

  https://www.arduino.cc/en/Tutorial/BuiltInExamples/AnalogReadSerial

  has been modified avoiding the delay() function and using 115200 Bd as 
  state-of-the-art instead of 9600 Bd.

// lastMeasurement stores the time in msec when a measurement takes place
unsigned long lastMeasurement =    0; // msec
// delayTime defines the time in msec between the last and the next 
// measurement
unsigned long delayTime       =    1; // msec

// Count counts the loops performed between two measurements
unsigned long Count           = 0;

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 115200 bits per second:
  Serial.begin(115200);
}

// the loop routine runs over and over again forever:
void loop() {
  // Increment Count with every loop
  Count++;
  // check if the last measurement has been performed (at least) delayTime ago
  if (millis()-lastMeasurement >= delayTime){
    // if yes: Store the new measurement time
    lastMeasurement = millis();
      // read the input on analog pin 0:
    int sensorValue = analogRead(A0);
    // print out how many loops have been performed
    // between the last and the recent measurement
    Serial.print(Count);
    // print a TAB 
    Serial.print("\t");  
    // print out the value you read:
    Serial.println(sensorValue);
    // Reset Count
    Count = 0;
