How to Transfer Data Using Led (li-fi Technology)

Li-Fi stands for Light Fidelity. The technology is very new and was proposed by the

German physicist Harald Haas in 2011 TED (Technology). I will show a simple experiment based on li-fi.

Step 1: Components Needed

1)led

2) aux cable

3)68ohm resistor

4)9v battery and connecter

Step 2: Connection

Step 3:

Now we need

1) 2 speakers

2) audio board

3) solar panel

5)9v battery and connecter

Step 4:

Now our simple circuit is complete.we can transfer audio signals using led and solar panel
