I needed this and appreciated it.
Little thing I would suggest is to edit out the part where you redo the light that didn't work (12:00). I know it's good to know how to fix things but for basic tutorial I prefer to just follow steps that just works. (Maybe video could be something like "here's way 1, 2, 3, 4, done. and now if you want to edit your signal you can do this..")
Don't worry about video not doing so well. It is valuable for beginner like me
