• KidWind LED Board (3)

To connect to the KidWind LED Board, use wires with alligator clips at the ends. Connect the positive terminal of your power source to the side marked RED (+) by slightly parting the alligator clip jaws and inserting both jaws into the two holes next to the LED. Connect the negative terminal of your power source to the side marked BLK (-) in the same manner.

While the KidWind LED board is intended for use with KidWind wind turbine and solar panel kits, it can also be used in physics classes for investigations about diode behavior and Planck’s constant.
