i am planning to do a project on automatic bell system using atmega16.please help me to get code and circuit.

automatic bell system using atmega 16

In today’s life, everyone gives importance to time. Time does not wait for anybody. Everything should be performed in time & with accuracy.
Now a day’s school/college bells are operated manually. Hence there is a big question of accuracy. Also there is necessity of manpower and
money. Hence here we have presented a system, which saves our manpower and money & also give highest accuracy. A bell is a percussion
instrument used in schools and colleges that indicates the students when it is time to go to the class in the morning and when it is time to change
classes during the day. No other instrument can do such a work. So it is an important instrument in both primary and secondary schools and even in
the industries and other businesses where the bell timer plays a critical role throughout the day. Clock towers can be heard over long distance
which was especially important in the time when clocks were too expensive for widespread use. And also due to literacy awareness the number of
colleges, schools and institutions are rapidly increasing. At present bells for periods in schools are operated manually. After every class, one
employee is engaged into operating the bell. Automatic college bell helps us to avoid this. This design takes over the task of ringing the bell in
colleges as the bell would ring automatically at the schedule time. It has a Real Time Clock (DS1307) which tracks over the real time. When this time equals to the bell ringing time, then the relay for the bell is switched on. The real time clock is displayed on LCD display. This is very wonderful design to control the working of college bell.
