How can i create a code for my name

How can I make a code in which my name appears in a matrix of leds Thanks for your support I’m new to this topic

We need a lot more details. How are the matrix of LED's connected? Do you have a library that lets you write text to it?

what are the dimensions of the matrix?

You don't need any code just to make your name appear. Just hardwire the matrix so the right lights are on.

Scrolling, panning ? Google for Arduino LED matrix display - then move forward from there.

Light up all of them and then tape off the ones you don't want visible.

Or something like this is involved

prog_uchar scrollText[] PROGMEM ={ "nikolas"};
