The implementation of a Light Emitting Diodes (LEDs) dot matrix moving message display system which shows a text containing 23 characters (i.e., GREAT DEPT. OF ELECT. ENGRG) is achieved in this paper using a PIC16F648A microcontroller. The microcontroller is programmed using assembly language, with MPLAB software and a PIC programmer .The LEDs are controlled by signals from the microcontroller and decade counters in a sequential manner which results in the moving message. In this paper, the authors make use of a 498 dot matrix display made up of 392 low power Light Emitting Diodes (LEDs).
