Hello,
I'm building the robot "Otto". I would like to add a mini matrix on the front. Who could explain to me the modification branching scheme and the right code..
Thank you
Otto biped

Do you already have the matrix? If so, can you provide a link or datasheet? If not, check here:

There’s quite a lot of sample code for matrices + Arduino, but most take up quite a few pins.
