Automatic Volume Control That Will Work With Any TV/Remote

INTRODUCTION

The device would consist of a microphone connected
to a PIC12C67X. The user presses a learn button
which sets the volume level. As the volume changes,
the microphone senses the volume and feeds it into the
A/D port of the PICmicro™. The PICmicro™ sends an
infrared signal (similar to a remote) to the TV to raise or
lower the volume.
In learn mode, the PICmicro™ reads the microphone
level and stores it as the reference level. As it monitors
the volume, it compares the volume to the reference
level and adjusts accordingly. This ensures minimal
background noise
