Description

Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes). Unlike standard longs unsigned longs won't store negative numbers, making their range from 0 to 4,294,967,295 (2^32 - 1).

Descripción

Las variable long sin firmar (unsigned long) son variables extendidas para almacenar números, y almacenar 32 bits (4 bytes). Por el contrario que las variables long estándar, las unsigned long no almacenan números negativos, haciendo que su rango sea de 0 a 4,294,967,295 (2^32 - 1).

to:
  Serial.print("Tiempo: ");
  tiempo = millis();
  //imprime el tiempo desde el inicio del programa
  Serial.println(tiempo);
  // espera un segundo para no enviar cantidade masivas de datos

Example

long time;

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

Parameters

    long var = val;

  • var - your long variable name
  • val - the value you assign to that variable
