Transmitting Music with Visible Light - Using an LED to make an Optoisolator

Описание к видео Transmitting Music with Visible Light - Using an LED to make an Optoisolator

A simple physics-related project to broadcast music using an LED. Hook the audio outputs from a headphone jack up to a circuit with an LED that is being powered by a battery. The signal from the audio output will rapidly modulate the output (the brightness) of the LED. You can then use a photovoltaic cell (a solar cell).hooked to a voice amp, speaker, or crystal earphone to pick up the light signal and convert it to sound. Using am LED to send signal from one circuit to another is the basic idea behind an optocoupler or optoisolator.
