Abstract: A considerable advancement has been made in automation in the world over the decades;automation is very very essential for every sectors
like a home or industry.New and low cost design is implemented.This project finds a wonderful use at primary and secondary school levels as well as in
colleges where the teaching sections can span over eight periods including breaks. The prime advantage of this project is that the bell rings at the start
of every period without any human intervention to a great degree of accuracy and hence succeeds the manual task of switching on/off the college bell on
time. This project uses LAN to work. Both Hardware and the App should be connected to the same Wifi network
