Music By Light
The circuit given here generates music in tune with the light.
One IC 555 is used as an table multi vibrator although. We can also use two transistors in place of this IC as shown in figure. In both the circuits one LDR is used. As light falls on LDR of both circuits, current begins to flow. The value of this current, depends upon the intensity of light falling on the LDR.
IC 555 produces audio- frequency according to flow of current and we can hear panoramic sound and music.
