The mini fan module blows a gentle breeze when you apply a voltage. The plus and minus signs indicate the direction in which the circuit fan operates. We suggest attaching ribbons or string to the circuit fan blades to create more dynamic motion!
Please note that the Coin Cell Battery Adapter doesnt have enough juice to power the Fan or the Motor with Wheel Module. Youll need the 9V Battery Adapter or the USB Adapter to power those.
