This study presents an alternative design for a notice board known as a PC based digital notice board on scrolling LED. Key features of the project design include availability of a PC interface and scrolling of messages. The PC interface enables the message on display to be changed at will using computer interface software from any computer that has the RS 232 port. The scrolling of messages from right to left enables the notice board to effectively display messages that are longer than its length. The scroll function and changeability of message on display when combined yields a versatile notice board.
