thankyou for taking so much time for me, the basic thing is i get the idea of writing the code, its not that i want to use STATE MACHINE , its only i need a easy way of writing a program for multi-tasking and as i searched the forum i found that example of 8 LED and 8 Buttons and your are right about the debounching thing.

Iam reading the code and trying to understand it i hope if i ask some questions related to this you will not mind you only have to give me hint i will check the code my self. And iam really thankful that you gave me so much time.

regards,
Amir hayat
