Simple light barrier – Part 2

Currently, until August, I’m writing on my Bachelor thesis, so I have not much spare time for researching and writing blog posts.

I tested out my light barrier circuit as described in Simple light barrier – Part 1, but it did not work. The LED I used to inidicate the signal was always off. So I will have to rework it and then I will post another part of this series.
