Advanced Circular System with Audio System
Since past few years, circulation of notices in any organization or institution was never been a short-term procedure. It consists of lots of paper work duly signed with higher authorities and human labor for its circulation throughout the campus and to the employees, students, etc. Many companies are manufacturing video or audio systems like CCTV, public announcement system, programmable sign boards, etc. which are complex in nature and difficult to expand. To overcome such problems and to reduce the expenditure of time and money involved, the development of simple and low-cost circular system with audio system is presented. Real time advanced circular system with audio can be controlled by mobile application using personal computer, mobile phones or laptop. The connection between mobile application and audio system uses Li-Fi connection. Mobile application is used to send notices. In this paper, a system is proposed to wirelessly transmit short notices using Li-Fi to reach students quickly in the classrooms.
