Replaces the manual switching of the hood in the School. It has a built-in real time clock (DS1307) that keeps track of the real time. When this time is equal to the bell time of the bell, then the relay for the bell lights up. The bell timing of the bell can be edited at any time, so that it can be used in normal class times as well as in exam times. The real-time clock is displayed on the LCD. The pic microcontroller is used to control all functions, get the time through the keyboard and store it in your memory. And when the real time and the Bell time are equal, then the bell is turned on for a predetermined time.
The need for an automatic school / college bell is now a necessity that has evolved with the revolution in technology and momentum in the educational system where time is a major factor affecting the educational system where time has to be exact. Man's power can also be saved with the use of the automatic school bell as it is not to be operated manually and labor can be saved is also more accurate than manual bell systems. The time that is an important factor in all our lives has to be used correctly and is a very efficient device for time management. The university bell is a simple project that implements the real-time use with its properties as an alarm with further improvements.
