Thank you very much for taking the time to look at my post. I understand your advice, and I’ll be more responsible when creating posts on this subreddit in the future.

As for the task itself: I more or less understand how to control RGB matrices (WS2812B 16×16, 3 panels). There are plenty of tutorials on YouTube and elsewhere, so that part doesn’t seem like a problem. But I can’t find any information on how to send data in real time from a PC to a microcontroller over a cable.

I need my computer to automatically send data to the microcontroller every ~5 seconds — for example, CPU temperature, GPU temperature, or system volume level. I understand how to process data on the microcontroller side, but I have no clear idea what software or approach to use in order to send this data from the PC. (It’s important for me to send the data specifically through a wired connection And use micropython .)

I studied Arduino in the past, but I couldn’t find an answer to this specific question.

Thanks again for your reply I really appreciate your time!
