Use Cases I
  • User
  • Phone receives user input
  • Select range using encoder 
  • Phone (Android Application)
  • Scan song list from the phone
  • Send the list to the server
  • Receive suitable radio station from server
  • Display desired radio station on the phone
    display
  • Transmit signal with desired radio station info
    to Arduino
  • Receive the final state of the radio from Arduino

6
Use Cases II
  • Server
  • Receive information from song list
  • Match this information against music database to
    find genre
  • Find the radio station which covers the genre
    best
  • Send preferred radio station information to phone
  • Arduino
  • Receive current radio station information from
    radio
  • Receive desired radio station information from
    phone
  • Compute most preferred radio station based on all
    phone in range
  • Report the status of the radio back to the phone

7
Use Cases III
  • Radio
  • Send Current station info to Arduino
  • Set new radio station based on signal from
    Arduino
