Controller for Christmas lights WS2811?

Question

Arduino

I want to do something similar for the New Year: https://www.youtube.com/watch?v=uQUWTC6ptFw&featur...
In the video, the author indicates that he uses the Arduino Mega 2560 as a controller. Is it possible to use something simpler, some kind of Arduino Nano or ESP8266 board? If so, are there any pitfalls in such a replacement?
Disclaimer: no experience with boards at all, but there is programming experience

Answer 1

The WS2811 uses addressable serial control. That is, both uno and esp8266 have enough legs. As for the memory used - take it and compile the required code under uno - ide will show the amount of memory used, I think there is nothing super complicated there, and there will be enough memory.
