Diy Arduino, Plc Lighting/dimming Controllers

Curious if anyone’s delved into constructing a light dimming and timer function controller to mimic the natural daylight progression. Also if anyone’s thought about any advantage to doing so?
I see some of the big names lights have controllers, but for us DIY’ers like to know if anyone’s gotten past first base on actually doing something similar...

Not personally but there are people around the web that have them setup!

Outside of the cool factor theres less shock to the plants ramping from 10%-100% over a few hours. People say its easier for them to adapt but no personal experience! If you go that route please share

Ive dove into timing controllers for running irrigation on Arduino. Took a little while. When it comes to that I just suggest getting something from opensprinkler. Their software is legit and easy to use. Specially if you aren't going to be the only one messing with it.

As far as making a timer controller for what you are talking about it shouldn't be too hard. There is already a couple premade libraries on the site (playground) for timers that would be pretty simple to make work for what you are looking for. The big bonus would be wiring in a temp sensor for high heat shutoff. Adding stuff like that in would be a cake walk once you get the basic's going. The relays for the triggers aren't too expensive depending on how many lights you are talking about. Sketch is pretty easy to use. Take a look @ https://playground.arduino.cc/Main/LibraryList/#Timing to get an idea

You can always cheat a little and check out their github for ideas https://github.com/OpenSprinkler

This is prob going to be overly complicated for something simple like a lighting controller though. Just note if trying to use any of that directly they have a bunch of added in components (wifi, lcd,buttons ect)
