Picture of DC motor as a generator

 

Steps

The DC motor is a ready made generator that will generate electricity. All that you have to do is turn the Axle of the generator using a mechanical outside source of energy .

To show that I dismantled a damaged HP printer and take  the  DC motor that responsible for paper out shown in pictures and connect it  to LED array ,  4 LED connected in a specific polarity and the other four LED connected in reverse polarity ,so when the shaft rotate on clockwise ,4 LED will be on due to  forward bias and the other  off due to reverse bias  and vise versa  in case of anti- clockwise rotation.
