    Automatic College Bell System


    1 in stock (can be backordered)


    This project is a Prototype model of “Automatic College Bell System”. This design finds a tremendous use at primary and secondary school levels as well as in colleges where the teaching sections can span over eight periods including breaks. The advantage of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence takes over the manual task of switching on/off the college bell with respect to time. It uses Real Time Clock (DS1307) which tracks the real time. The scheduled time results are compared with that of a clock, however, some drift is noticed, which is negligible.  The microcontroller “atmega8/168/328” is used to control all the functions; it gets the time through the keypad and stores it in its memory. When this programmed time equals the real time then the bell is switched on via a relay for a predetermined time. The bell ringing time can be edited at any time, so that it can be reused again and again at normal class timings as well as at exam times. For this a microcontroller has to be programmed using the C language or assembly language for controlling the circuit.

    Key Words:  Micro Controller, Bell system, Time Control etc.
