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

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.

Sequential processing Phone Connections are initiated in a serialized manner Each phone’s 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

Objective Automated DJ Assistant/Playlist creator

Automatically compiles a playlist of everyone’s music Prioritizes the most popular songs to optimize partying

Development EnvironmentInitial 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 don’t need to carry their own

speakers Initial project idea – songs collect influence currently playing radio
