Simple question deserves simple answer and not a sermon.
Where are you guys getting such picky attitude?
And some of you even do not read the question - where did the pin 0 came from ?are they true?or i must use bool arrays instead of int??
You MUST NOT use bool type...
- bool is not standard C/C++ type
- HIGH or LOW is also not C/C++ standard
3, You should always use smallest size of variable type to accomplish the task- Modern compilers let you specify the int size / type - such as uint8_t
You're new to Arduino, aren't you?
