Dot matrix displays are widely used in various aspects and for diverse purposes. They are used as means of advertising, displaying public service information, traffic notifications, and greetings note. Inspired by the functionality of dot matrix as message display, the aim of this project is to build a system that enables the transmitter block to transmit messages wirelessly to the dot matrix at the receiver block. Thiswill result in a timelier andaccurate message to be conveyed to public without having to be controlled by large workstation, heavy computers or any kind of software. The hardware of the system comprises of two blocks controlled by a PIC microcontroller respectively. The 4x4 keypad gives the input to the transmitter microcontroller and the Vacuum Fluorescent Display (VFD) acts as the transmitter display. The Dot Matrix is placed as the receiver display. RF hybrid transceiver pair that acts as the heart of the wireless transmission is interfaced to the microcontrollers using the encoder/decoder pair. The RF transceiver pair transmits and receives the data based on purely RF transmission without any assistance of Graphical User Interface (GUI). C languageprogramming becomes the basis of the operability ofthe microcontrollers and the control of the workflow of the system. This project is a potential platform for enthusiasts of electronics project to integrate the use of microcontrollers, C programming and wireless transmission and for further expansion for outdoor message displaying.
