Abstract
This research paper presents the design and implementation of an Auto Electronic College Bell system using Arduino UNO. The system automatically rings the college bell according to predefined timings without human intervention. The proposed system uses Arduino UNO as the main controller along with a 16×2 LCD display, buzzer, push buttons, and battery power supply. This automatic bell system reduces manual effort, improves punctuality, and ensures accurate bell timing. The system is low-cost, reliable, and suitable for educational institutions.
