Project #17

OBJECTIVE: To show how an integrated circuit can be used to

make real alarm sounds.

Build the circuit shown on the left by placing all the parts with a black 1

next to them on the board first. Then, assemble parts marked with a 2.

When you close the slide switch (S1), the integrated circuit (U2) should

start sounding a very loud alarm sound. This integrated circuit is

designed to sweep through all the frequencies so even hard of hearing

people can be warned by the alarm.

If the alarm sound was passed through an amplifier and installed into

a police car, it would also serve as a good police siren.

Alarm Circuit

Project #18

OBJECTIVE: To show how integrated circuits sound can easily

be changed to exciting space war sounds.

Build the circuit shown on the left by placing all the parts with a black

1 next to them on the base grid first. Then, assemble parts marked

with a 2.

When you close the slide switch (S1), the integrated circuit (U2) should

start sounding a laser gun sound. This integrated circuit is designed

to produce different sounds that can easily be changed. You can even

switch the sound on and off quickly to add sound effects to your games

or recordings.
