A Development of Feedback Mechanism for Microcontroller Based SMS Electronic Strolling Message Display Board. African Journal of Computing & ICT. Pp 59-68. Vol. 7. No. 4. http://www.ajocict.net/vol_7_2014_series.htmlhttp://repository.futminna.edu.ng:4000/handle/123456789/1780This paper presents the design and implementation of a microcontroller-based electronic scrolling message display board that enables real-time remote message updates via SMS, addressing the challenges of traditional signposting and manual paper-based notices. Targeted for use in educational institutions, public spaces, and advertising, the system utilizes a PIC18F4520 microcontroller programmed in C, and operates over the GSM network, allowing users to update displayed information from any location without the need for physical access. Additionally, the system includes a feedback mechanism to confirm successful message delivery, enhancing reliability and user convenience.Digital electronic display board is fast gaining acceptance and application in different spheres of life which include educational education institution, public utility places and in advertisement due to the problem associated with constitution of signposts and manually placement of papers on walls, buildings, and edifies which makes the environment look untidy. This paper presents the design and development of a microcontroller based electronic strolling message display board, which will be used to display messages and information in real-time via SMS. This microcontroller based electronic strolling message display board offers the flexibility to a user to control the message or information displayed without recourse to geographical location of the user, provided there is GSM (Global System for Mobile Communication) mobile network. It therefore eliminates the inconveniences of physically going to the display board to manually input information using a computer system. The paper also incorporates a feedback mechanism from the remote display board to ascertain that the message sent by the user has been displayed. The circuit of the devices is designed based on PIC18F4520 microcontroller and C-programming language is used to program the microcontroller.enGSM TechnologyFeedback mechanismPIC18F4520microcontrollerE-notice boardSMSArticle
