Led matrix+Infrared (IR) Remote control Arduino uno

Hello, i m not so good at code. I use a 8x8 led matrix and a ir remote control. When i press 1, the led matrix should color <- , for 2 it's ->, and for 3 it's ! ..... after every button pressing, the led matrix showes the symbol and then turns of.

Apart from having no idea what you’re asking, I strongly suggest you start at the beginning yes a switch, blink a LED, and forget the matrix for a couple of days. IDE examples, and online tutorials.

Then start putting together the little bits you pick up - to create a basic program that is heading towards your goal.

It won’t work at first, but you’ll learn a lot, then be better equiped to ask for help.

My teacher gave me these tasks... i m not into electronic teams

Then do not waste people's time.

That video’s a good starting point.
I can see 3 or 4 sub-projects to start working on.

The IR and matrix will make it a steep first project, but others have done it !

Start thinking !
