Arduino
Abstract:
In this paper a Arduino based intelligent
digital volume controller is presented to control audio speaker volume digitally and change volume
levels automatically in case of certain predefined incidents such as incoming
or outgoing people counts inside seminar hall. The device is constructed with Arduino
microcontroller and its software program being written in Embedded C language. Kits
includes intelligent decision making to change the volume level for certain
incidents. For how many times we have faced inconvenience to attend a change
the volumen depends of numbers in our room. Well, this device brings the
solution. It automatically tracks the peoples and detects a couns, and brings
down the volume to a much lower definable level. Similarly decrease happens for
outgoing peoples too.
