Hello. I am currently running 3 WS2811 neopixel rings off of one Arduino. I control them with pots. I would like to have a “show” for my rings so that they slowly change color combos and fade from one to the next on a loop. Do I need to upgragde from the UNO to make this work? THANKS
Someone else can probably answer better, but from my limited experience, you should be able to handle this all with an UNO. Assuming your patterns aren’t too crazy and you don’t have a lot of complex things that require a lot of program memory, the UNO should be just fine. I was able to get a lot done on the UNO controlling 6 different LED strips, an LCD display that contained a lot of items for a menu (which take up valuable space) just fine. I eventually did need to upgrade to a mega, but that was after I needed more and more menu options that the UNO simply could not handle.
Upgrading to a MEGA is ok too and I probably will. Here is the project idea:
Use distant sensors to make an interactive exhibit. When a person walks closer to the distance sensor, the color scheme changes on the WS2811. I can already do this, but I want the fade to be smooth between color combos and Ive worked a little with Fast_SPI in the past with poor results, but any dithering would be very helpful. Really appreciate any help
Are they the 60 pixel rings? 180 pixels on an Uno is eminently do-able, including a bunch of code to talk to sensors.
