Development of IOT Based Digital Display Board for Students’ Lectures Update

Technology is generally improving the advertisement sector and the use of electronic medium in communication system is on geometric rise due to its flexibility, attractiveness, speed and efficiency. Various methods of information dissemination have been adopted from the use of posters, traditional billboards to electronic billboards. This work presents the development of an IOT (Internet of Things) based display board for Engineering Students in Federal Polytechnic Ile Oluji, Ondo State, Nigeria for lecture update using wireless communication channel (wi-fi); this provides ease and comfort of updating the content from remote location in the wireless network range. The command is sent to the digital display board through the Mobile Application interfaced with the wireless module to give regular update and seamless communication with students.

The digital board basically contains a digital display module, a 5volts DC power pack, a wi-fi card, Microcontroller and Light Emitting Diodes. The administrator sends out message through the mobile led art light application to keep students updated on their lecture information. The text is received through the wireless module connected to the application and transferred to the microcontroller which decodes the message for users. The decoded message will automatically switch ON and OFF appropriate LEDs in order to display respective message sent which scrolls on the display. The display board can accept texts in different modes and styles as provided in the mobile application. The display board is useful in academic environment to regularly update students on lectures and other relevant information.
