Introduction: DC Motor As a Generator
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.
