======unsigned long   ======

====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).

====Example   ====

<code arduino>
unsigned 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);
}
</code>
====Syntax   ====

    [=unsigned long var = val;=]

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