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
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);
}
Syntax
unsigned long var = val;
var - your long variable name
val - the value you assign to that variable
