THE SMART DIGITAL AUTOMATIC BELL WITH TIMETABLE DISPLAY

The Smart Digital Automatic Bell with Timetable Display is a microcontroller-based system designed to automate the ringing of school/college bells and display the daily timetable digitally.The system eliminates the need for manual bell operation by triggering the bell automatically at pre-scheduled times stored in memory.A real-time clock (RTC) module ensures accurate timekeeping, while the controller compares the current time with the programmed schedule to activate the bell.Along with bell automation, an LCD/LED display continuously shows the current time, period number, subject, and teacher details according to the timetable.The timetable can be easily updated through buttons, a keypad, or wireless methods such as Bluetooth/Wi-Fi, making the system flexible and user-friendly.The system also supports special schedules for exams, holidays, or half-days.
