IoT Based Automatic College Bell & Messege Convener

Abstract: 

The world over the decades has made considerable advancement in automation; automation is employed in every sector whether it is home or industry. Here a new and inexpensive design is being presented. This design finds a tremendous use at primary and secondary school levels as well as in colleges where the teaching sections can span over eight periods including breaks. The advantage of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence takes over the manual task of switching on/off the college bell with respect to time.

 The project uses LAN network to work. Both Hardware and the App should connected to the same Wifi network.

Components:
1. NodeMCU
2. 16x2 LED Display
3. Buzzer (for Bell)
4. Small Buzzer  (for display notification)

Software Required:
1. Arduino IDE
2. Android Studio

Working:
When the system starts, it connects to the wifi network as we hardcoded into the  NodeMCU. Then it fetches the time from the internet and start the clock.
Now open the app, and start setting timings in the app. once the timings are set, it will be sent to the NodeMCU over the local network.
  The NodeMCU then starts to match the received timings with the real time it is getting from the internet. when the values matches, it starts ringing bell for some time.
 Also from the 'Notice' section, we can send a String notice to the Display board that we used in the project.

Conclusion:

Present day ringing the bell in colleges or schools are carried out manually. The

main disadvantage of this is that one person has to be alert for this. At the same time during that time he could not be engage in another task. To overcome from this, we have decided to prepare the circuit which will be operated automatically and the ringing of bell will start by it's own time. the time input can be edited as per requirements. This circuit is simple to prepare and easy to install. We can say that it will be much useful for colleges or schools or other educational sectors.
