A byte stores an 8-bit unsigned number, from 0 to 255.
I can understand the following line:
byte b = B10010; // "B" is the binary formatter (B10010 = 18 decimal)
But I also saw a use such as:
volatile byte state = LOW;
What does the last line mean here? Is that special for Arduino? I mean LOW is not a 8 bit unsigned number. LOW is not a number here.
