6. Motorized Pinwheel

It's time for another instructional video from Massimo Banzi, and this time he’s showing us how to make a motorized pinwheel with Arduino. To do this, Banzi will be controlling a DC motor using the Arduino board so that he can spin the wheel at different speeds. However, creating a motorized pinwheel has its own set of unique challenges. For instance, a DC motor works at a higher voltage than the Arduino. This means that it requires more current that an Arduino pin can provide. This is, of course, a difficult problem to overcome, as too much current will burn and destroy the Arduino pin. So how will Banzi overcome this obstacle? Well watch the video to find out...
