The aim of this project is to design a textual display system based on light emitting diode (LED) dot matrix array powered by solar energy. It involves taking the device from an initial concept, through a design phase, to constructing a prototype of the product. The system consists of the display unit, which is powered from a photovoltaic (PV) module and a battery. The nature of the design will allow the display to be mounted anywhere outside where it is needed. Also, microcontroller programs are developed to generate characters for each display board and the encoded characters are stored in the memory of the microcontroller. During this process, the data is sent to the LED dot matrix for display.
