Hello everyone! First-time poster here.
So, I've been banging my head up against a wall with this project for a while now, and I was hoping to get a bit of expert guidance. Instead of me vomiting 1000 words trying to describe what is a relatively complex circuit (for a project like this), I think I can boil it down to this one simple question highlighting a concept I don't quite understand.
Why does this setup (see attached img) make the LED strip blink off/on for a split second a couple of times per minute seemingly at random? If I remove the ground wire from PSU2, the random flashing stops.
I know it doesn't make sense from this diagram why I would want to connect the ground wire of the second PSU. There are several things I've left out for the sake of asking as clear, simple question as possible. Any light anyone could shed on this for me would be extremely helpful. Thank you!
