 ==== Komunikacija ====
-Komunikacija s modulom se ostvaruje asinkronom serijskom UART komunikacijom. Potrebne su dva digitalna izvoda: Tx i Rx na Arduinu koji se spajaju na Rx i Tx izvode (UOČI: Rx→Tx; Tx→Rx) na mp3 modulu. Za rad mp3 modula potrebno je dovesti i napajanje (GND i +5V) s Arduino Uno razvojne platforme. Na Arduino Uno razvojnoj platformi odnosno na ATmega328p mikrokontroleru postoji sklopovlje za asinkronu serijsku komunikaciju koje je spojeno na USB kako bi se mogla ostvariti komunikacija s računalom. Zbog uhodavanja i nadogradnje sustava asinkrona serijska komunikacija sa mp3 modulom ostvarit će se programski. Pritom će se koristiti ugrađena biblioteka [[https://www.arduino.cc/en/Reference/SoftwareSerial|SoftwareSerial]] koja se već nalazi u Arduino IDE.

 ==== MFRC522 ====
-MFRC522 modul je RFID čitač/pisač proizvođača NXP Semiconductors koji je namijenjen za očitavanje pasivnih RFID  oznaka propisanih ISO/IEC 14443 protokolom. Komunikacija između modula i RFID oznaka se odvija na 13.56 MHz. Komunikacija je ostvarena SPI komunikacijom linijama: MISO, MOSI, SS, CLK. Nedostatak: mali domet. Napredak: Zapis info o proizvodima na RFID oznaku (engl. //tag//).

+===== Bluetooth modul =====
+Bluetooth modul HC-06. Odabran zbog jednostavnog rukovanja. Serijska komunikacija izvedena softverski. Jednostavno spajanje na Android mobilnoj aplikaciji.

+====== Prototipno kućište ======
+Uređaj je prenosiv pa je napajanje izvedeno baterijom nazivnog napona 9V. Napredak: punjive baterije, prekidač
+Za lakše rukovanje sustav je smješten u plastično kućište. Zbog malog dometa RFID čitača isti je postavljen izvan kućišta. Također izvan se nalaze i slušalice.

 Ako dođe do greške prilikom povezivanja preko bluetooth veze, sustav može komunicirati izravno nakon očitavanja jedinstvenog koda proizvoda preko .mp3 modula odnosno reproducirati glasovni zapis s informacijama o proizvodu.

+==== Kreiranje projekta ====
+<font 12pt/inherit;;blue;;inherit>Nakon uspješne instalacije razvojnog alata potrebno je kreirati novi Android projekt. Kod stvaranja projekta potrebno je unijeti proizvoljno ime projekta. Korišteno ime je  CKGE_TMP_i SPVP_projekt CKGE_TMP_i . Stvara se novi direktorij istog imena u kojeg se spremaju programski kodovi, biblioteke te resursi potrebni za aplikaciju. Nakon toga potrebno je unijeti verziju platforme za koju se projekt izrađuje. Odabrana je verzija  CKGE_TMP_i API: 19 Android 4.4 (KitKat) CKGE_TMP_i  što je relativno stara verzija Android operacijskog sustava, ali je time omogućeno da se aplikacija može pokretati na većini mobilnih uređaja jer je pokretanje moguće i na svim novijim verzijama Androida.</font>
+<font 12.0pt/inherit;;inherit;;inherit>Pri kreiranju novog projekta, stvoren je novi  CKGE_TMP_i Activity CKGE_TMP_i  koji prikazuje grafičko sučelje koje vidi korisnik pri pokretanju aplikacije. Potrebno je odabrati  CKGE_TMP_i Empty Activity CKGE_TMP_i  i dodijeliti mu naziv  CKGE_TMP_i MainActivity. CKGE_TMP_i</font>
+===  AndroidManifest.xml  ===
+<font 12pt/inherit;;inherit;;inherit>Kako bi aplikacija ispravno radila potrebno je u datoteku  CKGE_TMP_i AndroidManifest.xml CKGE_TMP_i  dodati potrebne dozvole za korištenjem  CKGE_TMP_i Bluetooth CKGE_TMP_i  sučelja.</font>

+<font 9pt/inherit;;inherit;;inherit><uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /></font>
+<font 12.0pt/inherit;;inherit;;inherit>Potrebno je i navesti sve  CKGE_TMP_i Activity CKGE_TMP_i  java razrede koji se koriste u aplikaciji. Korišteni su  CKGE_TMP_i MainActivity CKGE_TMP_i ,  CKGE_TMP_i ProductInfoActivity CKGE_TMP_i  i  CKGE_TMP_i ProjectAboutActivity. CKGE_TMP_i</font>
