I tried to connect the proteus circuit and the code but for some reason it still doesn't work can you point out the problem I put the code that the schematic has drawn

Hi,

Forum rules say:
Only you know what "doesn't work" means
Please tell us what your circuit or code is supposed to do and why it "doesn't work".When you come in and say "it doesn't work" or just "it has errors", that means NOTHING. There could be a million things wrong and no one will know where to look.
