Moderator edit: I added CODE TAGS and merged the two threads because I thought they looked similar. If they're not, let me know and I'll split them again.
please help me the above program works correctly but some times it hangs in the middle the upper half works correctly but when the button program hangs some times it has give o/p when i/p goes high to low i.e edge trigger similarly for button2 it has give o/p when i/p goes low to high edge triggar for both buttons i/p is same
