Automatic ringing bell final year ECE project
Nowadays time plays an important role in our daily life and people run behind time as this factor doesn’t wait for anybody. Are the college bells or school bells operating automatically and accurately? Absolutely not, because most of the bells are operating manually and inaccurately. In order to overcome the problem of wasting lots of manpower and capital for correct ringing of bell several electronic circuit projects have emerged. We can save money and manpower by operating the bells automatically by means of using electronic circuit projects which comes under a list of major projects for ECE students.
This project is mainly based on automatic ringing of a college bell and musical clock is an exception. The bell we are going to design consists of an inbuilt real time clock which can be adjusted to ring at any real time but in this scenario the real time refers to the college ringing time. The micro-controller AT89s52 controls all the functions of the real time clock and the information whichever it gets are stored in its memory whereas simultaneously the real time is displayed on the LCD display.

In terms of the circuit design, the 220V ac current is converted into 12V ac current by means of a step-down transformer from the power supply. Then the converted 12V ac current is again converted into 12V dc current by means of a full wave rectifier. These type of electronic circuit projects are accompanied by certain relays for protection purposes and in this automatic ringing bell project, 12V dc current is used to operate the relay switch and the and 5V dc current is used to operate microcontroller AT89s8252. The software programming also comes under consideration and the ring timing can be set at any number of time by the user. The main advantages of undertaking this project includes smaller size, light weight, automatic college bell ringing at accurate time and time editable assistance. Final year project for electronic engineering students plays a vital role in getting an opportunity for their higher studies or job purposes etc..
