This paper presents the recent ongoing popularity of IOT (Internet of Things) technology and using the IOT LoLin NodeMCU v3 board a new way of scrolling text notice or advertisement on dot matrix display. The concept presented here is a smart way of scrolling text notice or advertising using the latest IoT enabled technology. The implemented design presently is used for important notice display on dot matrix display board at a common place visible to all students. Professors can send their notice/message to students by their cell phones using designed android application in MIT App Inventor 2. Any authorized person can access the notice/advertising board globally. The device is embedded with the scrolling led matrix display and controlled by IOT NodeMCU receiver. Once the IOT receiver gets connected with internet it will assign a specific IP address. The designed application sends text for advertisement using this specific IP address. IOT technology and its challenges are very concerned research topics, the presented paper and working prototype design is one of the applications of new technology. The prototype designed here with full product implementation can be used at many places. For example, Schools, Colleges, University, Playground, Bank, Railway Station, Airport, Bus Stations as well as running public vehicles.
