Hi all.. I need to create a lighting system control for several rooms that must sequentialy turn on and then off with a defined time delay, after they are all on, they will then turn off at the same pace as they turned on. There are several rooms, we might need to change that number in the future, and they have some distance between them. This process will just continue indefinitely.
So my question is what would be the best implementation for this, specially with the timing of the lighting? And we would need to do this without using microcontrollers.
