Introduction: Smart Thermostat
In this instructable we look at how to build a Smart Thermostat. What makes this thermostat so smart you ask? Here is a list of some of its smart features:
- It can be controlled by your Android device, which gives you one less reason to get up from the couch or get out of bed.
- High accuracy temperature measurement capability. The cheap thermostats that are in most homes can have error ranges of +/- 2 degrees!
- High resolution temperature settings to go with the great temperature accuracy, if you have a very slim temperature comfort zone this will give you the temperature setting resolution to hit your zone.
- No more trying to change the temperature or search for a setting with only one or two buttons and a tiny screen, this thermostat comes with a lot of buttons and a large display for making easy and quick changes.
The project is laid out in a series of three videos. The Arduino code can be found on GitHub (link provided in video). You can access the Andriod App .aia file using this link: https://dl.dropboxusercontent.com/u/26591541/Smart...

I LOVED your videos. However, in the second video you "promised" that you were going to show how to include a power supply for all the digital electronics, but it wasn't in the third video. I'm very interested in an easy way to power the digital section off the available 24VAC. Have you done that for this design or some other version?
