Hi, I have some question about the receiver side . You use the LED to receive. Why do you use the photodetector or photodiode?

I am not good at English ,so please forgive my poor english.

A led is used to minimize the cost and ensure selectivity to receive only the emitter color (a blue LED will received only blue light). I can also answer in French if needed.
