Hold down the press switch (S2) for a few seconds and then watch the
red LED (D1) as you release the switch. The LED flashes briefly but
only after the batteries (B3) are disconnected from the circuit. This effect
is much easier to see in a dimly lit room.

Hold down the press switch (S2) for a few seconds and then watch the
LEDs on the disco motor (DM) as you release the switch. The LEDs
flash briefly but only after the batteries (B3) are disconnected from the
circuit. This effect is much easier to see in a dimly lit room.
Do you know why the LEDs
flash? They flash because the
motor in the disco motor (DM)
uses a magnetic field to spin the
shaft. When the switch is
released this energy creates a
brief current through the LEDs.

WARNING: Moving parts. Do not
touch the fan while it is spinning.
