Re: Lighting control system using Crozet microcontroller

Yes I tried a bit of ladder logic, I originally considered the
Telemechanique controller, but it fried my brain! I have a degree in
computer science which probably doesn't give me the same kind of
skillset as electronic engineers have...

Why is it that most of these controllers are made by the French?
