AB A field-programmable gate array is used as the controller of a system that is going to be incharge of sending data through visible light. The transmission will be carried out with an LEDlamp and the data will be modulated in On Off Keying, encoded in Manchester and finally apacket will be formed using the RS-232 protocol. For all this, a transmission module has beendesigned together with the relevant electronic circuits. On the other hand, the transmitted datawill be received by a photodiode and whose signal will be appropriately conditioned so that it canbe detected by the reception stage that will be in charge of decoding the transmitted signal andobtaining the original signal.For the transmission stage, it was necessary to design an electronic circuit that essentiallyconsists of a buffer to be able to raise the 3.3V voltage from the Nexys development board to 5V,which is the supply voltage of the LED lamp.On the other hand, for the reception circuit, a TL082 operating amplifier is used in negativefeedback that allows us to condition the signal from the sensor, being a photodiode in our case, tothe reception pin that of the receiver module for the decoding of the signal.
