This paper based on the working principle of cloud security system i.e. how the cloud is capable of keeping data safe and the date stored in the cloud cannot be accessed by anyone except the authorized one. The system consist of various components such as LED Matrix, ESP8266, power supply etc., The system is made in such a way that it can be used to display messages, important announcement, legit schedules via LED matrix which is controlled by ESP8266 module. There are various types of displaying system across the globe which has made our life easier, but our system offers more convenience, easy to control, data over cloud can easily be displayed, 100% accurate and the more important thing is, it preserves a lot of time. So based on these problems we had researched how to secure and control time and the system is very inexpensive. If this system is applied in every school and college areas then wastage of time can be controlled easily.

LED Matrix, Esp8266 Module, Proteus App, Cloud, DC Source, Feeder.
