The byte type stores a 1-byte (8-bit) unsigned integer number, from 0 to 255.


The byte type is provided for compatibility with Arduino. However, it is a non-standard extension. The standard C++ type for storing an 8-bit unsigned integer is unsigned char; we recommend using that instead. (Your code will still work on an Arduino).


byte b = 134;
