Music Box

Model SCP-04

When you turn on the slide switch (S1), the music integrated
circuit (U1) plays a song then stops. Each time you press
the press switch “doorbell button”, the song will play again
and stop. Even if you let go of the press switch, the
integrated circuit keeps the song playing until it has reached
the end of the song.

Modify the circuit in project #1 by placing the press switch
(S2) across points A & B.

WARNING: SHOCK HAZARD -

Never connect Snap Circuits
to the electrical outlets in your
home in any way!

Musical Doorbell

Momentary Alarm

The Snap Circuits Kit uses electronic blocks that snap onto a clear plastic base grid to build
different circuits. These blocks have different colors and numbers on them so that you can
easily identify them.
on the clear plastic base grid first. Then, assemble parts marked with a 2. Install two (2) “AA”
batteries (not included) into the battery holder (B1).

When you turn on the slide switch (S1), the music integrated circuit (U1) plays a song and
then stops. Each time you turn on and off the slide switch, the song will play again and stop.

Musical integrated circuits are used to entertain young children in many of the toys and
chairs made to hold infants. If the music is replaced with words, the child can also learn
while they are entertained. Because of great advances in miniaturization, many songs are
stored in a circuit no bigger than a pinhead.

Build the circuit shown by placing all the parts with a black 1 next to them

When you turn on the slide switch (S1), the music integrated
circuit (U1) plays a song then stops. Each time you press
the press switch “alarm button” after the song stops playing,
the song will play again, but only while you hold the button
down.

How does the speaker make sound from electricity?

An electric current in a wire also has magnetic properties. A
speaker has a coil which concentrates the magnetic effects
to move a tiny magnet. When the magnet moves it creates
a change in air pressure which travels across the room. You
“hear” sound when your ears feel the air pressure change.
