    With no code, no chance to get effective help.
    Anyway, as a general advice, the obvious recommendation is to change the character map.

    Guess you'll start with defining a character generator matrix and determine how many rows and columns are required, variable character width?

    Do you mean "save all sentence in memory map " and just scroll it?

    Not the sencence, but the alphabet bitmap. The standard strategy is to program the code in different functional layers: In short, one to define the character (in general, in static memory), other to scan each character, and another to scan the whole phrase.

    Anyway, if you have already done that, I was expecting you show your code to ask what should have to do.

    Re: Arabic Language LED MATRIX Dot matrix display using ARDUINO or PIC or AT89S51

    May be the problem itself is that arabic letters consist of different symbols means something. In this case it is impossible to save single character for each letter. So, there are two ways how to solve it - build some sort of character contructiong engine wich will combine symbols to letters or simple store the whole word as a sprite and reproduce it on screen at needed position. Anyway, I don't see any problems to stop me to solve this task both ways. May be autor just need more practice first?
