Li-Fi Audio Transmission — Send Sound with Laser & Solar Panel (DIY Project)
.
.
.
In this video, I demonstrate a Li-Fi audio transmission project where sound is transferred from a mobile phone to a speaker using light.
The audio signal is transmitted through a laser diode and received using a solar panel, which converts light back into an electrical signal.
This project explains the basic concept of Li-Fi (Light Fidelity) and Visible Light Communication (VLC).
It is useful for engineering students, diploma students, and electronics hobbyists.
🔧 Components Used:
• Laser Diode
• Solar Panel
• TIP41C Transistor
• Capacitors & Resistors
• 3.7V Battery
• Speaker
