Last winter was a cold one. Going into the phone app and turning the heater on is a known solution to help ensure maximum efficiency of the battery. With the winter coming soon, I wanted a better way to do it. Instead of the app, wouldn’t it be cool if I had a button to press that warmed my car up for me? I can leave it next to the dog’s leash so that when I walk her in the morning all I had to do is press the button and go about my business.
Yeah, I know. The phone app works. Isn’t it good enough? No, that isn’t the point. I wanted to tinker and have some fun! I wanted to make a button with little lights and wires on a bread board. Besides, what would you rather do? Push a button or digg out your phone and go through that whole process? So, time to build a button.
