Basically, LI-FI transfers data through visible light, and as we know the bandwidth of visible light is 10,000 times more than Radio waves, so more data can be transferred through the light in a short period of time.
What is Li-Fi?
Li-Fi (light fidelity) is a bidirectional wireless system that transmits data via LED or infrared light. Through this method, we are making a li-fi Transmitter Circuit for audio data transfer.
This circuit can transmit the audio by the IR led in form of Li-fi.
