Temperature sensor!!

My TMP36 analog temperature sensor has arrived! It cost $2 and can measure from well below freezing to well above boiling with 1/10 degree accuracy! You just plug it into an analog input in your arduino and it's awesome. This is a great component.

Also, I mentioned this project to my friends Aaron and Brad, both of whom are engineers. They both got really excited and offered to help, which felt really good. Aaron actually has a degree or something in electrical engineering, which is awesome. I'm hoping to learn how to use gears instead of expensive servos to turn my shower knobs, and he may be able to help. Yay!
