When party animals are rolling in the deep, they
want to hear music that they like. However, all
party animals like different music, and the DJ
ends up playing songs that the DJ enjoys. Party
animals would prefer a DJ to be able to pick
songs based on the audience preferences instead
of his own. This will help the DJ keep the party
animals happy and the party alive by allowing him
to see what songs from his library will be liked

• Sequential processing
• Phone Connections are initiated in a serialized
  manner
• Each phones list is recorded before moving to
  next operation
• Stores playlists reported from multiple phones
  (to tally popularity)
• Blocking requests
• Finish current processing before handling next
  phone

Results

• Objective
• Automated DJ Assistant/Playlist creator
• Automatically compiles a playlist of everyones
  music
• Prioritizes the most popular songs to optimize
  partying

Operating Range (radius) Mean 17.2 ft,
Standard Deviation 4.3 ft
Development Environment

• Initial set of experiments
• Prototype completed, works within 40 ft. range
• Successfully handles up to 50 phone connections
• No user input required, aside from powering up
  app
• Future Expansion
• Move system to a larger Arduino to include more
  features
• Include speaker AUX out so users dont need to
  carry their own speakers
• Initial project idea songs collect influence
  currently playing radio station

• Hardware
• Arduino Pro Mini 328
• FTDI Basic Breakout
• Bluetooth Mate Gold
• LED Display
• Software
• Party Animal Android App - Accesses the user's
  music library and sends song list information
  to the Arduino
• Arduino Firmware - Stores a prioritized playlist
  of all the songs it has seen from any phone.
  When one song ends, the Arduino is notified
  and sends a request to a phone to begin playback
  of the next most popular song.

Look Ma! No hands!
