Smart Push-button for Garage Door

Step 7 Final notes

That is it, just a simple and elegant garage door indicator with some expandability features.

Everyone at home is appreciating the new indicator, even friends and family that come for a visit think it is a neat idea.

I have been asked a couple of questions more than once so this is where I will make note of them. I covered why I decided to use the BlinkM instead of a simpler non-flashing LED at the beginning of this Instructable and I have a feeling that there will be another question regarding why did I bother with the flashing green when the garage door is closed instead of just being it turned off completely (the first question my daughter asked me after I finished installing it). My answer is that I like to know when any system is working and the little green flash every 8 seconds tells me so.

Another question that popped up in my case is why bother when you can just open your door and see if the garage door was left open?
Well that is exactly what I was trying to avoid, having to open the door to check, especially on a cold night.

Also, if you build it, you can do as you like ;)
