Push the switch (S2) to light the

lamp (L4) and spin the motor (M1).

Notice how the lamp gets a little

less bright as the motor speeds

up.

Light & Motion

Project 13

Light Dimmer

Use the preceding circuit, but

remove the glow fan from the

motor (M1). Push the switch,

and watch how the lamp

starts out bright, but gets dim

as the motor speeds up.

Next, hold the motor top with

your fingers so it can’t spin,

then push the switch and see

how bright the lamp is.

Project 14

Limiter

Push the switch (S2) and you

hear the horn (W1), but the

lamp (L4) will not light and the

motor (M1) will not spin.

The lamp (L4) lights and the motor (M1) starts

spinning when you install the last 3-snap wire.

Push the switch (S2) to bypass the lamp and make

the fan speed up.
You can swap the locations of the lamp and motor to

make a lamp with 2 brightness levels, but be careful

not to touch the fan when pressing the switch.

WARNING:

fan during operation. Do not

lean over the motor. Fan may not

rise until switch is released. Do not

launch fan at people, animals, or

objects. Eye protection is

recommended.

The faster the motor is spinning, the

less electricity it needs. The more

electricity flows, the brighter the lamp

gets. The motor needs the most

electricity when it starts up, making

the lamp brightest. Without the fan,

the motor can spin fast and needs

little electricity, making the lamp dim.

The horn doesn’t need much

electricity, but it limits how much

can flow through the circuit, not

allowing enough to light the lamp

or spin start the motor.
