How many neopixel strings

Post by wdickenson »

I am outfitting friends shuttle model with some lighting. My plan was to run a set of neopixels around in a long string. But it would be a lot simpler if I could group sets of lights (Running lights, engine lights, cabin lights) into individual strings. But it would require running it from one Uno.

That likely to work ? any gotchas ?

Thanks

You can drive multiple strings from one UNO. Each one will require one pin, so you could have as many as 18 (up to 20 is possible, but it can cause upload problems if you use the Tx & Rx pins)

Thank you, that makes the code much more readable !

(and the wiring less so but those are the breaks)

If you want discrete light sources you could use some (or all) of these https://www.adafruit.com/categories/275 You don't say how big the model is so I'm not sure which would be best.
