Hi all,
I'm experimenting Visible Light Communication. A basic setup would be having a LED (white) with a driver and a photo-diode circuit.
For example i would like to send this string"HELP". In contrast a binary steam would be send by switching on-off the LED (too fast for naked eye to see).
The photo-diode would be like a receiver.
I'm pretty weak with circuit design.
From my idea, it would be connecting a ADC to the photo-diode.
Anyone has better idea of making this circuit???
Many thanks!!
My final implementation would be leveraging the TCP stack for data transmission.
How can i covert the output from the ADC to be compatible with a TCP stack.
It's just another medium used, besides Wi-Fi and Ethernet (RJ45)
