Chapter 2 Automatic Music Control System
Automatic Music Control is the automatic operation of the House and Smoke Alarm from the
MP3 player. One of the tracks on the player is coded with commands that are synchronized
with the music. When the music is played, the main control board in the Smoke Alarm Base
Unit decodes commands on the tracks. These command signals are sent to the Smoke Alarm
and the lights in the House to create a synchronized performance with music and animation.
