Where to learn basic coding for Otto


I am a high school librarian with a 3D printer - I am printing Otto, and I'll be purchasing a basic DIY kit tonight. I have ZERO knowledge of coding, but I'd like to learn a bit to make him move. I've watched some YouTube videos, but they don't seem applicable to what I would need to know. Can you refer me to somewhere that I can begin learning? Thanks. :)

MaxMatrix mirrored

by dose13

Hi, I am currently working on the Otto quad (https://www.thingiverse.com/thing:3418147/files) and facing a mirrored display on the 7219 Led Matrix.
I read some comments that MaxMatrix.cpp library needs to be changed. I found a comment in the Ottoś builder group on Facebook by Manuel Capinha that solved it for me:

void MaxMatrix::writeFull(unsigned long value) {
for (int r=0; r<5;r++){
for (int c=1; c<7; c++){
setDot(c,r,(1L & (value >> r*6+c-1)));
