Abstract -
reliable, real-time systems to disseminate important information to students in an efficient and eco-friendly manner. Traditional methods of communication such as printed notices, physical circulars, and manual announcements are gradually becoming obsolete due to their limitations in accessibility, timeliness, and resource consumption. To overcome these challenges, the integration of technology in communication systems is vital. One such modern solution is the development of a smart LED Advertising Board based on IoT e-Circular Notification through Bluetooth, which automates the process of sharing information with students.
In the contemporary digital age, the demand for efficient, rapid, and cost-effective communication systems within educational institutions is ever-increasing. Traditional methods of notification dissemination, such as printed circulars or physical notice boards, often suffer from delays, limited visibility, and high resource consumption. In response to these limitations, this research paper presents a comprehensive design and implementation of a Bluetooth-based IoT-enabled LED advertising board system, aimed at delivering e-circular notifications to students in real-time. The proposed system leverages the power of microcontroller-based hardware integration and wireless communication to enable dynamic, remote content updates on a P10 LED matrix display, enhancing visibility and operational efficiency in campus environments.
This project proposes an innovative approach to digital information broadcasting within school or college premises using an LED matrix display panel, commonly referred to as a P10 display, integrated with a microcontroller (Arduino Uno), real-time clock (DS1307), and Bluetooth module. This system enables administrators or teachers to send electronic circulars or updates from a smartphone or computer directly to the LED board, which then displays the information in real time. The solution not only eliminates the dependency on paper but also ensures that messages reach students in a centralized and immediate fashion.
This project revolves around the use of the Arduino Uno microcontroller as the central control unit. It interfaces with the DS1307 Real-Time Clock (RTC) module to maintain accurate timekeeping for time-sensitive notifications and announcements. The core display unit utilizes a P10 LED matrix panel, a cost-efficient and energy-saving display capable of rendering large and clear text in both scrolling and static formats. The system architecture is designed to support real-time text display, making it suitable for broadcasting class schedules, examination alerts, event reminders, emergency notifications, and administrative announcements.
The backbone of this system lies in the use of IoT (Internet of Things) and Bluetooth technology to establish wireless communication between the administrator's device and the display unit. By using a Bluetooth module, the system becomes cost-effective and simple to operate, allowing short-range yet highly effective communication. Meanwhile, the use of the DS1307 Real-Time Clock (RTC) module ensures that the display shows the accurate date and time, giving it an additional utility as a digital clock.

The Arduino Uno, a versatile and widely used microcontroller platform, controls the entire operation of the system. It reads the time from the RTC, accepts messages from the Bluetooth module, and manages the scrolling or static display on the P10 LED board. The P10 display is a high-visibility matrix panel capable of showcasing characters and symbols clearly, even from a distance, making it suitable for classroom corridors, school entrances, or administrative offices.
