Abstract:Cilj projekta je bil izdelati sprejemnik frekvenčno moduliranega signala, ki bo majhen, prenosljiv, poceni, energijsko varčen in baterijsko napajan. Preučili smo več vrst sprejemnikov. Odločili smo se za izdelavo sprejemnika na superheterodinskem principu. Pred izdelavo končnega izdelka smo izdelali tri prototipe. Za razvoj prototipov smo uporabili razvojno platformo Arduino. Po razvoju prototipov je sledila izdelava končnega izdelka oziroma tiskanine, ki odpravi potrebo po Arduino platformi. Sprejemnik omogoča izbiro med radijskimi frekvencami in pomnjenje izbranega števila radijskih postaj. Delovna frekvenca je prikazana na zaslonu s tekočimi kristali. Demoduliran signal oziroma zvok je predvajan na zvočniku. Zaključni projekt zajema načrtovanje in razvoj sprejemnika, izbiro strojnih komponent, pisanje programske kode, razvoj treh prototipov in končnega izdelka, vključno z njegovim testiranjem. Končni izdelek predstavlja izhodišče za nadaljnji razvoj sprejemnika. Možne so številne izboljšave oziroma dodatne funkcionalnosti: avtomatski frekvenčni odziv sprejemnika, prilagajanje kontrasta zaslona s pomočjo senzorja za svetilnost, programska nastavitev glasnosti in izdelava vodoodpornega ohišja.

Title:RECEIVER OF FREQUENCY-MODULATED SIGNAL
Abstract:The goal of the project was to produce a frequency modulated signal receiver that will be small, portable, cheap, energy-efficient and battery-powered. We studied several types of receivers. We decided to make a receiver on the superheterodyne principle. Three prototypes were made before the final product was manufactured. For development of prototypes we used the development platform Arduino. After the development of prototypes, the production of a final product or a printing paper was followed, eliminating the need for the Arduino platform. The receiver allows you to select between radio frequencies and to select the selected number of radio stations.The operating frequency is displayed on the liquid crystal display. The demodulated signal or sound is played on the loudspeaker. The final project covers the design and development of the receiver, selection of hardware components, program code writing, development of three prototypes and final product including its testing. The final product is the starting point for the further development of the receiver. A number of improvements or additional functionality are possible: automatic frequency response of the receiver, adjusting the contrast of the screen with the aid of a luminance sensor, volume adjustment software and the production of a waterproof housing
