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 slide switch (S1) and you will hear a siren and music
together while the lamp (L1) varies in brightness. Push the press
switch (S2) and the fan spins, while the sound may not be as loud. The
fan may rise into the air when you release the switch.

This circuit is similar to Project #101, but the fan will fly a little higher
since the sound circuit no longer drives the lamp (L1) and therefore
uses less battery power.
