Good idea.

Yes use parallel

स्म

il existe des connecteurs à clipser qui evite les soudures

so where's the problem then? just resolder that shit and be over it...

bro cod mil sakta hai ky

Need ws2812

Everything is same in Arduino Uno as in Arduino nano. U can use same code as well as same pin configuration. U just have to select the specific type of board before uploading in Arduino IDE.

@@priyaop5040 in the tools section what should be its programming

Theoretically infinite given an adequate power supply. The bottleneck would eventually be the data packet size for very large arrays vs the desired refresh rate. I think the WS2812b only has a refresh rate of 400Hz, so you'd probably max out pretty quick for large scrolling text displays. Using something like the WS2813, with a 2000Hz refresh rate, would be better for a large display. But to answer your question, you'd have to calculate the baud rate for n LEDs, then see if that results in an overall refresh rate of 26hz or higher (lower than that the movement starts to look choppy).

Did you find the code please?

ok
