Gemma MO Dotstar
I am using a Gemma MO and coding with Arduino code. I have attached a light sensor and two wearable led's. How do I turn off the Dotstar led on the Gemma? When I power on the Gemma I don't want to see any light.

Re: Gemma MO Dotstar
The DotStar generally won't show anything unless programmed to. If your sketch is not doing anything directly with the DotStar, but it's still "on", then it may be from whatever last talked to it, like the bootloader for example.
Best is to just explicitly turn it off in your user sketch code. Can adapt the strandtest example:

and then just fill with 0 (black).
