Hello everyone! Today I purchased my first Arduino components. I haven't really dabbled with DIY electronics for 20 years; when I was a kid I had one of those 200-in-1 radio shack kits and managed to do pretty well with it.
Arduino is something that has always had my attention and I have wanted to play with but never found a reason to use. I'm the kind of person that needs to solve a problem. Last week my fairly new, expensive, programmable HVAC thermostat died. It was hot out so I quickly looked up the wiring diagram, jumped some of the wires and enjoyed cold air. XD - Enter the Arduino!
My HVAC unit is easily by 4 contact points.
* Common +24 volt feed
* Fan/Blower
* Heat
* AC
I dug around amazon and came up with a quick list of stuff available on Prime (Inventory at the bottom)
I know nothing about Arduino, but chose the Uno because it seems to be the most used in projects of this size. Would a nano work for something small like this?
I'm very excited about all of this and look forwarding to keeping this log updated. That's all the data I have for now, I have a ton of research to do. If anyone has comments, thoughts, ideas, or links to existing projects that would be beneficial to me please post them up.
