OBJECTIVE: To build a circuit with

light and sound that change and repeat.

Project #39

Blinking

Double

Flashlight

Build the circuit shown on the left and turn

it on. The lamp (L1) alternates between

being on and off while the speaker (SP)

alternates between two musical tones . . .

like someone is flipping a switch, but at a

very consistent rate. Periodic signals like

this are very important in electronics.

Project #38 Periodic Sounds

Project #36 Space Battle (II)

OBJECTIVE: To show

another way of using the

space war integrated circuit.

Build the circuit shown on the

left, which is based on the

circuit in the Space War

Project #19. Turn on the

switch and you will hear

exciting sounds, as if a space

battle is raging!

The motor is used here as a

3-snap wire, and will not spin.

Project #37

Silent Space

Battle

OBJECTIVE: To show another

way of using the space war part.

The preceding circuit is loud and may

bother people around you, so replace

the speaker (SP) with the LED (D1),

position it as in Project #32. Now you

have a silent space battle.

In the circuit at left, replace the speaker

(SP) with an LED (D1); position it as in

Project #32. The lamp alternates between

being on and off while the LED alternates

between being dimmer and brighter.

OBJECTIVE: To build a circuit with two

lights that alternate.

WARNING: Moving

parts. Do not touch

the fan or motor during

operation.
