Description

Returns the number of microseconds since the Arduino board began running the current program. This number will overflow (go back to zero), after approximately 70 minutes. On 16 MHz Arduino boards (e.g. Duemilanove and Nano), this function has a resolution of four microseconds (i.e. the value returned is always a multiple of four). On 8 MHz Arduino boards (e.g. the LilyPad), this function has a resolution of eight microseconds.

Note: there are 1,000 microseconds in a millisecond and 1,000,000 microseconds in a second.

Parameters

None

Returns

Number of microseconds since the program started (unsigned long)

Example

to:

Descripción

Devuelve el número de microsegundos desde que la placa Arduino comenzó a correr el programa. Este número eventualmente volverá a 0 (overflow), luego de aproximadamente 70 minutos. A 16 MHz, en las placas Arduino (por ejemplo, Duemilanove ó Nano), éstas función tiene una resolución de cuatro milisegundos (por ejemplo, el valor devuelto es siempre múltiplo de 4). A 8 MHz, en placas Arduino (como LilyPad), tiene una resolución de 8 microsegundos.

Nota: En un milisegundo hay 1.000 microsegundos y 1,000,000 microsegundos en un segundo.

Parámetros

Ninguno.

Devuelve

El número de microsegundos desde el inicio del programa (unsigned long)

Ejemplo

Changed line 23 from:
  Serial.print("Time: ");
to:
  Serial.print("Tiempo: ");
Changed line 25 from:
  //prints time since program started
to:
  //Imprime el tiempo desde el comienzo del programa
Changed line 27 from:
  // wait a second so as not to send massive amounts of data
to:
  // espera un segundo para no enviar datos una cantidad exagerada de datos.

micros()

Description

Returns the number of microseconds since the Arduino board began running the current program. This number will overflow (go back to zero), after approximately 70 minutes.

Note: there are 1,000 microseconds in a millisecond and 1,000,000 microseconds in a second.

Parameters

None

Returns

The number of microseconds since the current program started running, as an unsigned long.

Example

unsigned long time;

void setup(){
  Serial.begin(9600);
}
void loop(){
  Serial.print("Time: ");
  time = micros();
  //prints time since program started
  Serial.println(time);
  // wait a second so as not to send massive amounts of data
  delay(1000);
}
