xulingxuling23:
i mean when i want to use it my arduino doesnt detect the library (no in display example)
Go to \arduino-***\libraries\your_fuzzy_logic_library_name\examples
Make there two new folders \sample01 and \sample02
Place file sample01.ino into \sample01 and sample02.ino into \sample02
Start IDE
The problem is that each example file must be placed into the folder with the same name.
