Project #73 Directional Wind Lights
Hydro Lights
Place the water wheel on the mottor (M4) and connect it to the circuit
as shown. Hold the motor under a water faucet so the water wheel will
“catch” the water as it falls. The LEDs (D1 & D5) should light.
Your parts might stop working if water gets inside them. Let them dry out
and they should be fine.
Build the circuit, and place either the wind fan
or the water wheel on the motor (M4). To
make the LEDs (D1 & D5) bright, blow on the
wind fan from above, or blow into the “curves”
of the water wheel.
