Project 132 2-Light Symphony of Sounds
This circuit is similar to to project 126 (Symphony of Sounds), but
adds the lamp (L1). Note that the lamp does not snap on the battery
holder (B1), but is secured by the 2-snap wire on level 3.
Turn on the slide switch (S1); you hear sounds from the music &
alarm ICs (U1 & U2), and the color LED (D8) and lamp light. Push
the press switch (S2) several times to add sounds from the space
war IC (U3).
You can also use the variants in projects 127-131 here.
