2026-07-14 (Tu) EWC_Mobile Lights and feedback

I wanted to get the addressable LEDs working, so I checked the pin I used and noticed there was a faint light on the board that disappeared when I unplugged it from the prototyping board. It could be a data port. I tested the FastLED example on the controller's pin, and it worked, so I integrated it into my code. Since I did not have any serial feedback via USB, I displayed some troubleshooting information on the built-in screen. The LEDs were supposed to be cycling, one at a time, but it was skipping them sporadically. I printed the LED address that should be lit, and the problem disappeared. I think my time-based triggering for the light cycles was triggering multiple times, and the controller refreshing the screen delayed it enough that it stopped being a problem. I also printed the prandom note on the screen to practice displaying multiple lines of text.
