Introduction: 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
