    Multiple LED Matrices with Arduino

    I am not sure if I understand what you mean by "changing the direction of the words"The current code starts displaying the first character on the right-most matrix (index 0) and then it scrols the text moving to the left.This means that your matrices are aligned with matrix 0 on the right and matrix 3 on the right and the text scrolls right to leftTo achieve the effect of the text entering through the left-most matrix and scrolling left to right, you should change the code. Alternatively you can:- reorder physically the matrices: make matrxi index 0 the left-most and matrix 3 the right-most.- reverse the order of the string you want to write (e.g. "DLROW OLLEH" instead of "HELLO WORLD"
