The project mentioned below is the wonder of the electronic age.  People get surprise when they hear this sound from the project.  It surprises mostly those persons who do not know any thing about electronic.  These can be used in place of door bell, car reverse horn etc.  This project works on the supply of 3 volts.  COB is the main component in this project.  Its complete name is [Chip on board].  Like IC or transistor COB does not have any number. This is a special kind of IC module programmed for different songs, sound etc. It is mounted on the PCB and can not be separated from it.  Project produces the sound of [Jai Mata Di] and [ALLAH-HO-AKBAR] Other components in this project are for biasing of COB and amplifier.
