That all makes perfect sense, thank you for the information. I was able to get GPIO working with this help but I think in a future iteration, CAN will be the better option. Can't thank you all enough. May have some more questions upcoming :)

Thank you for the suggestion! I'm running out of time but let's explore this. I'm just trying to coordinate Hueshift between the Teensys to the naked eye so I'd think 20ms or less would be fine. I do have another coordination I will be doing, basically taking some flex sensors and sending...

Thank you. I had seen the "common ground" requirement before but I assumed since the power supplies were plugged into the same electrical circuit (same power strip, same house), that would be "common ground". But I see now that assumption was not correct.

Yes, thank you for pointing that out. I took that out, cleared some other things that seemed unnecessary after going through line by line and trying to understand what each is doing. When it made sense to me and still had a problem, figured out that it probably isn't the code, it is the GPIO...

Hi. Background: I was sort of involuntarily tasked with the LED lighting for an art project I'm doing with some friends. I don't have hardly any coding experience, thus I'm trying to use some AI assistants (have tried ChatGPT and Claude) for help, and very disappointed with the results, to...
