WebHow to use highByte() function with Arduino. Extracts the high-order (left most) byte of a word (or the second lowest byte of a larger data type). Learn highByte() example code, reference, definition. What is Arduino highByte(). WebNumber are generally stored in binary, so, for instance 135 is represented as 10000111, i.e. 128 + 4 + 2 + 1. Bitread allows you to inspect a specific bit of a number, so bitRead (135, 0) = 1, bitRead (135, 5) = 0. In particular, passing 0, 1, 2 or 7 as argument to bitRead (135, *) would return 1, whereas otherwise it would return 0.
