I am doing research about Led-to-Led data transmission, guys do you have any idea or source how to use LED as receiver (Rx), Mention your references, YouTube links whatever you think important to this. Your contribution is highly appreciated. Thank you.
If you're using LED as data transmitter your receiver would probably not be LED as it's light emitter rather than receiver.
You could build something that receive the data from the LED light and translate the data back into something human can understand.
You could Google about gadgets that can translate data from LED back nto something readable/understandable.
