Arduino and 8x8 Dot Matrix(White) to Indicator Board

Projects General Guidance
1

I am trying to find out how to get the Above, to show up on a Indicator Board for a Model Railway. I am trying to learn more of Arduino sketches' and perhaps variables to have this Indicator Board a single number 1,2,3,4,5,6,7,8,9,0.
TIA

If you google “8x8 matrix Arduino “ you will
Find loads of results

Can we get more information on the matrix? Is it just an 8x8 array of LEDs or does it have a built in controller like a MAX7219?

If it has a 7219 controller the Parola library makes displaying text, sprites and even animation pretty easy.

Thanks for reply, more reply to next reply

Thanks for reply, there is 8x8 and there is 5 pin in and 5 pins out, there is a Number on one side HL-M1388AW, I was told it would show white.
more later perhaps

That is a "bare" 8x8 matrix of LEDs, no controller.

Here is an Ali Express page for that display.

This shows the pin out.

Type: common cathode.

A MAX 7219 would make using that matrix easier. Only 1 resistor needed for current limiting and 3 pins to control the matrix instead of 16.

this is what I have

It would have saved me some time had you posted that right off. All the searching that I did was for nothing.

Is that chip a MAX7219? Do a search for "arduino 7219 tutorial".

Good luck,
I'm done.

I AM VERY SORRY, but I am very new at this ARDUINO stuff.
THANKS FOR YOUR TIME

Just in to inform you, that I was able to FIND that search, THANKS
