Snappy says there sure are a lot of
different sounds that can be made
with the music and alarm ICs.
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. Turn on the switch (S1)
and you will hear a siren and music together
while the lamp (L1) varies in brightness.
Modify the last circuit by connecting points Y &
Z with a 2-snap (on level 5). The circuit works
the same way but now it sounds like a machine
gun with music.
Now remove the 2-snap connection between Y
& Z and then make a 2-snap connection
between X & Y (on level 5). The circuit works
the same way but now it sounds like a fire
engine with music.
Now remove the 2-snap connection between X
& Y and then make a 2-snap connection
between W & X (on level 5). The circuit works
the same way but now it sounds like an
ambulance with music.
