My New Toy

Recently,I bought the other kind of microcontroller called Arduino. Before this one, I've played Basic Stamp in my lab, but just know a little simple concept. Because Arduino is cheaper than Basic stamp, I bought it for myself and hope I can learn some knowledge about electricity or autocontrol. However, although I have great interest of it, I suppose to study my TOEFL test first because the test date is coming~~~~ T.T
