DIY Weather Station with Bluetooth
by Matej Blagšič @ instructables.com:
Recently I attended a course in our University of Electrical Engineering and we were making ourselves a small weather station. It included learning about soldering, sensors and arduino. It was super fun making it with little kids and other high school kids my age. I will show you how you can build it yourself, what components do you need and explain you the code and how can you upgrade it with more sensors.
