Abstract

In this paper a Microcontroller based intelligent digital volume controller is presented to control music system and PC speaker volume digitally and change volume levels automatically in case of certain predefined incidents such as incoming or outgoing telephone call and pre-set alarm. The device is constructed with AT89S52 microcontroller, from ATMEL family with 8051 architecture, and its software program being written in C language.
