Set the meter (M2) to the LOW (or 10mA) scale. With the slide switch
(S1) off, make sure you have enough light on the solar cell (B2) for the
meter to read 8 or higher. Now turn on the slide switch and listen to
the music.

The meter is used to measure if the solar cell can supply enough
current to operate the ICs (U1 & U2).

Solar Music Space War Combo (II)
Use the circuit from project #564 but replace the speaker (SP) with the whistle
chip (WC). Now the light on the solar cell (B2) doesn’t have to be as bright for
this circuit to work. You can also modify this circuit by replacing the music IC
(U1) with the alarm IC (U2).
