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
