I’m super new to hardware in general, so I’m hoping someone can assist with how to hook up a neopixel ring (16 neopixels) to an Electron. I’ve been looking at tutorials and other projects like this tutorial about photon + neopixel and this Alexa project, and I’m confused about two things:
- In the tutorial about photon + neopixel, they say that I have to use a logic level converter (shown above) - is there a way to get around this requirement? Like, can I power the neopixel ring separately? If so, how can I do that? I have the particle maker kit, which has a 4-battery holder thing that I think I can use, but unsure if there are details i’m missing.
2… In the Alexa project, the photon seems to be hooked up to the neopixel directly, without this logic level converter (shown above). Does this mean that the Photon puts out 5V, but the Electron only does 3.3V? Can I just follow this wiring diagram using the equivalent pins in the Electron without any changes?
Would really appreciate any light you can shed about logic level converters and hooking up a neopixel ring to Electron. Thanks!
