Well, it works ok but the lag is bad. I had to put a hook into my other LED lib where the tight loops were but that way I could use a slider to control some motors as I change the led patterns. I’d really like to make an App that lets the user program their own patterns using a more intuitive interface. No user interface lag is needed if there are ways to check and set a few globals as the lops run.
This is a paper clip mounted to a motor. The rotation rate and LED refresh rate make interesting moire patterns but fastLED seems to be much better than the simple version I have now. I am glad others are also interested in getting fastLED, esp32 and App Inventor working so it’s easy to have fun creating, recording and playing back various pattern combinations.
