Sorry to disappoint you but 2.2.8 shows the inputs expect a connection to 12V, not to ground like many breakout boards.

The sensor you have chosen will not work with this type input. Perhaps Omron makes a version with the same physical dimensions that has the right electrical features. I take a look.

oh, and you're welcome

A quick look gave no results from Omron, you'll have to widen the search. Probably you will have to make a new mount to fit what you find.
The correct sensor needs to run on 12V input power and have a PNP transistor output, Also the output needs to turn on when the light is blocked.
Post a part number if you find a likely candidate.

AHH,
So fudge some 12v limits for now.
Then get the ess smoothie, with 5v I/o and a 5v I/o Bob, hook that to them in the future when fitting to be e 200w servos.
Great idea
