Long variables are extended size variables for number storage, and store 32 bits (4 bytes), from -2,147,483,648 to 2,147,483,647.
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); }
long var = val;
