Arduino Based Smart Bell

Abstract

In today’s era, many school/college bells are operated manually. But there is requirement of accuracy in operation. In schools/colleges, there are many digital clocks available with bells but they ring only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The Arduino uno is used for controlling all the functions, it gets the time through the keypad and stores it in its memory. The benefit of this design is that the bell rings at the start of each period without any human intervention to a great accuracy and hence takes over the manual task of switching on/off the college bell with respect to time. It uses real time clock device which tracks the real time. The scheduled time results are related with that of a clock; conversely, some irrelevant drift is noticed. When this programmed time equals the real time, then the bell is switched on via a relay for a predetermined time. Also, while ringing, this bell presents status of lectures of different classes, which are displayed on scrolling display.

Keywords: Arduino Uno, RTC, relay, LED scrolling display.
