Each LED Board has four surface-mount LEDs, one each in red, yellow, green, and blue. Connect to the board with two alligator clips in the double holes on either side of an LED. The board is marked with the words black (–) and red (+) to indicate polarity.
This is the same LED board that is included in the KidWind Solar Energy Exploration Kit, the KidWind Advanced Wind Experiment Kit, and the KidWind Basic Wind Experiment Kit. It is also included as part of the KidWind Power Output Pack, the Solar Energy Explorations Go Direct Package, and the Wind Energy Explorations Go Direct Package.
