hello community. I hope you are well
operation of the assembly when the obstacle is removed and when it is in place between the Led and the photodiode ?
a remote control tester is it possible with this assembly?

That's a pretty standard setup. What's your question?

Technically, yes. Of course you need to add a few things. Here is what you are describing - used commonly as an "end stop".



You need to hold the remote that you are testing right up to the unit, trying to hit the detector. It should be able to tell you whether "something" is coming out of the remote.

You would be able to tell more (like distance) using one of these.



But, remotes are typically encoded, not just a presence or absence / on or off. These are fun and very cheap kits that, along with a controller, you can play with.



If you have a time machine, you can go pick up one of these at the Shack  ;) .
