In these days of automation and advancement of technologies, the human efforts have been minimized for every aspect of life. Machines and systems with Artificial intelligence are replacing the role of Human beings from Pilotless Military Drones to Modern day intelligent cars. Machines are being used to replace operations and works of humans were there are chances of human error and Malfunctioning. If we neglect some acceptable errors, these systems do their jobs very effectively and punctually.
In the kit Automatic bell system a real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time.
In the kit automatic bell system here we have designed which can be used in colleges to indicate the starting of new lectures and commencing of classes based on real time using RTC IC and an alarm system. The user once has to set the timing of the start and end of lecture in the school schedule. The RTC will calculate the real time and feed it to the microcontroller in digital format. The microcontroller will match the data from RTC with the set times by the user and according to that generate the signal to trigger the alarm unit automatically.
