IR sensor circuit problem

This is my pcb design.......

No it is not, it is a schematic. It is a different schematic than you said you were using in the first post.
I asked:-

What you need to do is to post a photograph of how you have wired it up along with the code you are running.

If you are going to keep changing your story and refusing to cooperate with requests you won't win many friends here.
