I don´t understand, why when I call the Serial Monitor it starts in 0 (cero), It is a counter, I don´t restart the DUE, I hope that every time I call the serial monitor, the counter have any value, but why always start in 0.
Thanks.
// constants won't change. Used here to
/ set pin numbers:
const int ledPin = 13; // the number of the LED pin
// Variables will change:
int ledState = LOW; // ledState used to set the LED
long previousMillis = 0; // will store last time LED was updated
long interval = 500; // interval at which to blink (milliseconds)
unsigned int contador=0;
unsigned long tme;
void setup() {
// set the digital pin as output:
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}
void loop()
{
// here is where you'd put code that needs to be running all the time.
// check to see if it's time to blink the LED; that is, if the
// difference between the current time and last time you blinked
// the LED is bigger than the interval at which you want to
// blink the LED.
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval) {
++contador;
// save the last time you blinked the LED
previousMillis = currentMillis;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW)
ledState = HIGH;
else
ledState = LOW;
Serial.print("Time: ");
tme = millis();
//prints time since program started
Serial.println(contador);
// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
}
}
