Tiivistelmä
This project is primarily comprised of research on Visible light communication systems and methods for developing two prototypes in order to test out the link between them.
This is accomplished using various components such as LEDs, two different photodetectors and other passive components. The microcontrollers used are Arduino Uno’s and thus programs are written in C++. OOK-NRZ is used for modulating the data. The photoresistor prototype worked as expected, but the photodiode prototype failed to output any useful data.
Further testing of the links in terms of the SNR and BER could be beneficial in future projects. A good understanding of transimpedance amplifiers will prove to be useful in the design of a VLC system using a photodiode.
