In Arduino World, LOW means a value of 0 and HIGH means a value of 255.Not correct, in the Arduino world (which is C/C++) LOW = 0, HIGH means any other value, not just 255.
Not correct - HIGH is defined as 1 in "Arduino.h".
In C/C++ an expression is false if it evaluates to zero, and true if it evaluates to any non-zero value.
