Modify the last circuit by
connecting points X & Y with the
lamp (L1). The circuit works the
same way but now it sounds like
a machine gun.
Now remove the connection
between X & Y and then make a
connection between T & U with
the lamp (L1). The circuit works
the same way but now it sounds
like a fire engine.
Now remove the connection
between T & U and then make a
connection between U & Z. The
circuit works the same way but
now it sounds like an
ambulance.
Now remove the connections
between U & Z and between V &
W, then make a connection
between T & U. The circuit
works the same way but now it
sounds like a familiar song but
with static.
