A music to light modulator is a circuit that controls the intensity of one or more lights in response to the level of an audio input. The problem in older circuits is that there was a direct electrical connection between the lights using mains voltage (110 to 250V AC) and the amplifier circuit low voltage (9 to 12V) levels.

Activate the modulator and project the light beam into the fibre optic bundle. Bend the fibre optic bundle to demonstrate internal reflection and point at the solar panel. Modern communication systems use modulated signals carried by light beams in clear fibre optic cables. This forms the basis of the new LiFi technology and the NBN (National Broadband Network in Australia).
