    LED Matrix with Arduino

    I have used it with an Arduino ProMini so a ProMicro should also be ok. The pins in the instructable are defined as: LED Matrix    Arduino          Colour of wire in picture VCC               5V                   Red GND              GND                Black DIN                D12                 Yellow CS                 D10                 White CLK               D11            ...see more »I have used it with an Arduino ProMini so a ProMicro should also be ok.

    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"
