1. Make sure that the fuel cell is fully hydrated.
2. Connect the USB cable between the circuit board and the computer and verify that the
green and blue LEDs on the circuit board are flashing.
3. Make sure the graphic software is running on the computer.
4. On the computer display, click on the Connect button at the lower-left on the screen and
verify that a red plot line is slowly moving across the bottom of the grid display.
5. Adjust the voltage (vertical) scale to 1.88 volts.
Procedure:
Note: Please read through this procedure first before performing the experiment, as the
elements of the process go fast and require prior knowledge of what is about to happen.
1. Place the table fan directly in front of the wind turbine then switch it on to its highest
(fastest) setting. A plot similar to the one below should begin to appear. Notice how the
voltage quickly increases (but not as quickly as the battery or solar panel – more about
this later).
