/*
 * Room Status Display
 *
 * A remote Arduino sends serial data relaying the status of a room
 * on campus.
 *
 * If lights are on and it's loud, room is social.
 * If lights are on and it's quiet, room is study.
 * If lights are off and it's quiet, room is empty.
 * If lights are off and it's loud, room is creepy.
