We are living in the automation world, where everything in industrial and home automation is getting automated with the help of an advanced programmable controller. An automatic bell system for schools or institutions reduces the effort necessary to control an electric bell manually that gives alarm for certain intervals of time based on school or college timings. The proposed system uses a simple basic microcontroller to make the product affordable. Generally conservative methods need a peon or bell operator to control the bell system for every class and intermission in schools and also institutions. Such systems require plenty human efforts to do so, and need progress in order to become automatic – the ones that reduce human efforts.
The proposed system is very important in schools, homes and also industries. But, operation of this automatic instrument must have to be executed with an accurate time controller in an inexpensive way.
