Have you seen this series of posts?
Are you using the specified pins? It does make use of the SPI hardware I believe.
Looking at the picture, I'm unsure of your power connections.
The LED panels I have run on 5V only and it does look like you have maybe 12V connected as the Arduino barrel jack power seems to be the same as the panels. And the Arduino barrel jack needs to be at least 7V, not 5V.
Your Arduino will run ok on the laptop USB power but the LED panels will not.
Can you please clear up the connections?

For the next meeting 4th Nov. I will have a play with addressable LEDs.
They come in different packages. This is an example.
As is this...
Here are some libraries to add if you do not have them already.
See the postings about Josh's 5x8 matrix too.

These may be a good board to play with.

Aliexpress price $13 +$8 postage.
Have a look at this video. The guy in it has put a lot of work into getting a community going and has produced docs and code examples for this board. He does make a comment that there are other similar boards around so if you get one, check it is the correct one to suit the info.

I think it could be a very fun board to play with. Maybe even run a radio synthesizer?

Here is a great tool for playing with Arduinos.
It is an emulator that is described by Andreas Spiess ...
Hi youtube channel... https://www.youtube.com/@AndreasSpiess
My IC22S code on the emulator is here...

Have a play with this okwi emulator. It is a great bit of work!

Here is a neat H bridge for motor driving that is very affordable, at under $15 each from the normal on line stores.
It is rated at 6 to 27V, and 30A (43A Max) so can drive quite large loads.
These were mentioned in the video refereed to in post #56.
Here is an article on driving them from an Arduino.

I will bring some along for the next SADARC meeting.
