it seems to be some bugs or mistakes on this program?
sone help me plz

When you have a problem thats too big to solve you have to break it into smaller parts. For example you know that you are getting good results from everything but the output pins. Write a simple program to toggle the output pins. Build on it one piece at a time until you are back at the program you have now. That way you will know where you it broke.
