In recent times, Mobile and wireless technology have provided us with the mechanism to remotely control and update the content of a display board via SMS and other modern means. This work is aimed at developing a display system that fuses the functionality of wired, wireless, and mobile technology into a dual-face, double-layer SMS-based LED notice board capable of displaying memos, announcements, or notices received serially from a smartphone or PC via a terminal application on a P10 SMD LED display as well as forwarding the same information to some selected recipients mobile numbers through an inbuilt GSM feedback system. The system's performance is then evaluated based on its response time to the input message. Messages are transmitted serially to the notice board in three different communication modes (USB, Bluetooth, or Wi-Fi). Push buttons are used by users to alternate between the different working modes, making the system flexible in a variety of scenarios and compatible with wired and wireless communication protocols. The message is received by an ESP32 microcontroller and passed on to the LED board for display and the GSM modem. The notice board is equipped with an inverter power backup system to maintain uninterrupted operation in the event of an AC power outage, eliminating the weakness in the existing display of its kind and offering an alternative to paper for a timely and reliable way to post notices for intended consumers.
