Spacey Fan

Project Number: 104

OBJECTIVE: To build a fan with sound that is activated by light.

Description: Place the fan onto the motor (M1). Sounds are heard if light shines on the photoresistor (RP) OR if you press the press switch (S2), the fan may start to spin, but will only get to high speed if you do BOTH. Try various combinations of shining light and holding down the press switch.
