Desperate need of help

Hello! I am trying to program.. this:


I do not know what to search for, or if it could even work with the arduino online editor software, please help

it uses 4 8x8 led matrix

You've given us absolutely no information whatsoever. What help could you possibly expect? No one can read your mind.

Please read How to get the best out of this forum and follow the advice to be found there.

ok, what help I want to get is help on how to program one of these sticks, what even IS the name of it, the compatibility of the stick with the arduino cloud editor, a possible code to test if it works, the connections that I need to do and to be more respectfull.

Did you not even look at what you posted? Here it is.

Please explain what exactly anyone is to make of that.

I do not understand why the image hasn't loaded, but I will repost it

It's an LED matrix. Have you looked at the back? Are there any part numbers? Are the connections labelled? What did you find when you took a picture of the back and put it through Google Images?

Are you sure it is programmable?


yes, because it is led matrix(es) which are able to be programmed

but I don't know what code I would need to use to make it work

It might have a MAX7219. Look for MD_Parola examples.

I also found this when removing one of the matrixes

Useful (legible) pictures.

What is?

the single segment I posted is the same for the rest of the segments

This potentially looks like what you have?

yes, very much, but mine is blue, I don't know if it makes it a different version
