Thanks a ton @ratkins – I’d LOVE to read a full build breakdown post Burn; this is a really cool approach.
Heck, I posted in Hey 2023 Burner ms, what are you bringing to the Playa this year? - #12 by ZacharyRD my Playa wearable for the year, and ran out of time for a full writeup of implementation details myself – but doing exactly what you have here for pattern and brightness control was one of my stretch goals that very much didn’t happen. I was trying to just use the main PB onboard button pins to change patterns, and I was getting some weird issues (it didn’t debounce properly, that caused me to cut that out of the project in the interest of time.
After Burning Man / once the code you’re running on is not Beta / once you do a full write up, I’d love to enhance that helmet to do exactly what you’ve done here; it already has a sensor expansion board.
