LED lighting for our gazebo

GazeboDespite all the Domotica stuff going on every day, I was able to find the time to build a gazebo in our garden this summer. I finished this gazebo in late June. Well, not quite; I still have to take care of the lighting. And somehow, everything I build or do in my spare time just has to have a Domotica touch 🙂 This time, it’s the lighting. I could have chosen the easy way and just put a big bright light bulb in the middle for when it gets too dark outside, but that’s too ugly, easy and no fun at all.

So I contacted Marco Versluis of Mood LedLight and he offered to come over and have a look at the gazebo and discuss some options for some nice and good lighting. Although I’m not the type of guy who decorates the entire home inside and outside with flashing lights at Christmas time, I do like to have nice lighting in the garden during the time that it’s dark and we’re still downstairs; an example of this is a previous garden lighting project.

This time we chose to do the lighting with 6 RGB LED spotlights.RGB LED spotlight

At each of the 6 poles of the gazebo there will be a RGB LED spotlight which will light the pole and the inside of the roof. That should be sufficient to give good lighting while sitting under the gazebo on warm nights as well as a nice view from the living room when we’re inside.

OK.. I admit it, I just couldn’t resist buying a DMX decoder for those 6 RGB LED spotlights – so I can produce 256 x 256 x 256 colors, who wouldn’t want that in his back yard? 😉 And of course, these LED spotlights need to be controlled from my Domotica system, otherwise it wouldn’t be much fun, right?

I’m not worried about accomplishing this. I found a Arduino DMX shield that should take care of the DMX encoding. And since it’s an Arduino shield and I have some unused Arduinos here, this will be plug & play, hardware-wise. Developing a sketch to control it all from my domotica system shouldn’t be that hard either.

No, the thing that I’m thinking about most of the time is: what color should these LED spotlights produce? Just pick a color I (ehh, we) like? Neh, too easy. And I certainly don’t like some predictable color scenario that repeats itself every x minutes. Yuck!

Come on, my Domotica system has almost 900 device values, why can’t I create some RGB values out of all that constantly changing data and produce a real geeky lighting? (ah, that reminds me: I need a motion sensor for the gazebo and/or a button to override the geek-lighting scheme with something that’s more moderate and acceptable for non-geeks … 🙂

So basically, I’m looking for “something” that should produce a smooth changing, unpredictable RGB value based on device values originating from our house… There’s enough to choose from I guess… like using door/window open/closed status as bits for one of the 3 RGB bytes, or on/off statuses,  motion detection, total power usage for the R value, water usage for the B value…  well, I’m still thinking what to choose – suggestions are welcome!
