| Summary: | This paper proposes a system that enables a transmitter block to transmit messages wirelessly to
the dot matrix at the receiver block. Dot matrix displays are widely used in various applications for various
purposes. Among them are advertising board, public service information, traffic notifications, greeting note
and many more. The hardware of the system comprised of two blocks controlled by a PIC microcontroller.
The 4x4 keypad gives 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. The operability of the microcontrollers and the control of the workflow of the system was
developed using C programming language. 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 on outdoor message display. |
