Abstract
Cilj rada je realizacija prijenosa informacija putem svjetlosnih signala. Ostvaren je prijenos teksta u vidu brojeva i slova kodiranih prema Morseovu kôdu u jedinstveni niz točkica i crtica. U projektu se koristi Li-Fi komunikacija za slanje optičkog Morseova kôda. Razvijeni sustav uključuje implementaciju Li-Fi odašiljačke i prijemne jedinice. Android uređaj, odnosno kreirana Android aplikacija, predstavlja odašiljača i kodera spomenutog Morseova kôda te se šifrirana poruka šalje upotrebom ugrađene LED bljeskalice na telefonu. Na prijemnoj strani, fotootpornik prima bljeskove svjetla s telefona te ih šalje Arduino mikrokontroleru na dekodiranje. Zatim se na LCD zaslon ispisuju dekodirani alfanumerički znakovi kako bi korisnik usporedio dekodirane podatke sa onim podacima koji su se poslali s Android aplikacije. Ispisivanje na LCD zaslon korisniku omogućuje lakše uočavanje ispravnosti implementiranog sustava. Razvijeni sustav obavlja sve predviđene radnje te je krajnji rezultat funkcionalan, ali postoji potreba za poboljšanjem. Naime, korištenjem fotodiode umjesto fotootpornika, sustav bi mogao biti znatno brži od razvijenog u ovom projektu.
Abstract (english)
The goal of the project is the realization of the transmission of information via light signals. The transfer of text in the form of numbers and letters coded according to Morse code into a unique series of dots and dashes was achieved. The project uses Li-Fi communication to send optical Morse code. The developed system includes the implementation of a Li-Fi transmitter and receiver unit. The Android device, ie the created Android application, represents the transmitter and encoder of the mentioned Morse code, and the encrypted message is sent using the built-in LED flash on the phone. On the receiving side, the photoresistor receives flashes of light from the phone and sends them to the Arduino microcontroller for decoding. The decoded alphanumeric characters are then printed on the LCD display to allow the user to compare the decoded data with the data sent from the Android application. Printing on the LCD display allows the user to easily see the correctness of the implemented system. The developed system performs all the intended actions and the result is functional, but there is a need for improvement. Namely, by using a photodiode instead of a photoresistor, the system could be significantly faster than the one developed in this project.
