IOT Based Digital Led Notice Board Using Arduino UNO

This paper presents the implementation of a simple IoT-based wireless notice board. The proposed system utilizes Wi-Fi to communicate with a cloud database. The concept of a digital notice board begins with sending a message to the cloud using an Android mobile device. At the receiving end, an Arduino Uno equipped with an active internet connection is deployed and configured to receive incoming messages. Upon receiving a new message, the system alerts the connected LCD display, which then shows the message in real-time. Keywords: IoT, Arduino Uno, Notice Board
