In the circuit, the outputs from the alarm and music ICs are
connected together. Build the circuit shown and then place the
alarm IC (U2) directly over the music IC (U1), resting on two 1-
snaps and a 2-snap. There is also a 2-snap on top of the alarm IC.
Turn on the switch (S1) and you will hear a siren and music together
while the lamp (L1) varies in brightness.
OBJECTIVE: To combine different sounds.

Wacky Sounds
OBJECTIVE: To combine different sounds.
Build the circuit shown. Turn it on, press the press switch (S2)
several times, and wave your hand over the photoresistor to hear all
the sound combinations. You can make the sound from the music IC
louder by replacing the 100
Ω
resistor (R1) with the 2.5V lamp (L1).

OBJECTIVE: To combine different sounds.
Now remove the 2-snap connection between X & Y and then make
a 2-snap connection between X & Z (on level 5). The circuit works
the same way but has different sounds.
