i cant change my design because i want more brigtness on seven segment so i am using 4094.

You mean, you can't change the design, because it was given by the teacher, right?

friend plz try to help how i write coad for switch interfacing as post on this forum before.

This makes no sense. If you had understood the circuit, then you would be able to write the code. It's deadly simple.

And why the hell can't you tell us, where exactly you have problems in coding??
