Now one-day automation is becoming crucial in human life because it reduces human effort. Likewise, time is also important in the life of the individual to achieve success. The BELL automatic project assumes the task of ringing the bell in the school / schools and replaces the manual bell switching in the university / school. When the time is equal to the bell time of the bell, then the bell relay is turned on for a predetermined time. We can edit the ring time at any time so that it can be used in normal class times and even in test times.
This LCD screen is used for real time clock display. The keypad is used to edit the programming to ring the bell. Through this keyboard, the input will go to the EEPROM in which this program will be stored to ring the bell. Based on the programming relay of the microcontroller will operate and will turn on the buzzer for the specified amount of time. The AT89S52 Microcontroller helps you control all the Functions to get the time for the keyboard stored in your Memory.
