added upper L for Arduino Uno to preheating time

Browse source 
The literals for the preheating time are interpreted as int.
On Arduino Uno an int is 2 bytes in size, ranging from -32,768 to 32,767. Therefore, the calculated number of 3*60*1000=180000 does not fit in.
Added upper L to force the literal to long.
