741 operation amplifier is connected to audio oscilaltor, using Radio Shack 276-667 photoelectric cell in feedback loop. When the light shine on PC1, the resistance decreases, the earphone tone frequency declines too. When the light shine on PC2, the increasing illuminance makes the frequency rise. Selecting R4 can make the volume drop to needed degree. R3 is a balance controller of two photoelectric cells. (View)
