Abstract: The main objective of this paper is to implement an automatic collage bell using microcontroller. An automatic bell system for school or collage reduce the effort necessary to control an electric bell manually that gives alarm for certain intervals of time based on school r collage timing.
This paper helps to manage the schedule and works automatically according to it. You have to set the instructions at once and then it will work accordingly. You can see the entered data on the LCD screen. You can set many periods as you want. The timer represents in LCD is in seconds. Then confirm the time and a timer will start on the LCD. When the time is over the buzzer starts running. We used three major components which are Real Time Clock (RYCDS1307), 16*2 LCD module, and Arduino.
Keywords: Atmega32Microcontroller, Bluetooth module, RTCDS1307, LCD display , Relay, Buzzer.
