Has anyone tried to make police lights for an electric toy car with 2 Neopixel 4x4 matrix tiles and an Aruino nano every. Iv searched the internet and dont seem to find any projects using multiple tiles as independent outputs. Please advise.

Welcome to the forum This sounds very simple. Where are you stuck ? Do you know how to control one Neopixel matrix ? Have you tried adding a second one ? Why do the two tiles have to be independant when you could connect them together and control each part of the longer strip independently ?

So Im new to trying out Neopixel matrix tiles. Iv tried to use the Adafruit Neopixel library example to learn to use the tile. I changed it to accomodate 4x4 tiles which my electronic shop only had but iv failed to make it follow emergency light strobbing. On another project Iv successfuly made 10 …

What exactly do you want to display on each tile ?

Thats exactly what I was looking for. Thanx a million xfpd. I really appreciate you courtesy and patience. I hope Id be able to return the favour in the future.

Are you interested in how to make your own? How are you at writing and understanding coding? Ask me anything.

So Im basically understanding the syntax to be used. I understand the addressable nature of the leds ... I also understand the void and loop functions, the defining of the pin on the controller The including of libraries etc are good to know but i do have a difficulty understanding how the matrices …
