hi b,
This voltage of 0V across the two, when the light path is Open and Closed.
ie: Emitter to Detector is showing that the project is not going to work as you expect.

The problem is that you do not have any technical details of the two devices ie: Emitter & Detector, so that we can check if they are suitable for the project.
