Neopixel 12 Pattern Help for N00B

[ThatDamnGuy]

Hello,
I am new to the Neopixle & Arduino Gemma world, so far I love it. I am looking for some assistance with a project. I want to use my Neopixel 12 to replicate the Windows 10 Loading gif, but I am not sure how to even start modifying the defult sketch from the GitHub Adafruit NeoPixel Library. If anyone could help or point me in the right direction I would appreciate it!

Thanks William

I am not exactly sure which animation you want. I would start with something basic. The colorWipe function turns on one pixel at a time. Try modifying that function to just display a rotating single pixel. (hint: it takes just one additional line of code and it will include the expression ' i - 1 '). Once you get that you can try to get the 'tail' to look right if that is the animation you are going for. As you progress you will want to look at the remainder operator ' % ' and figure out how you can use it to keep your calculations within the ring pixel count. https://www.arduino.cc/reference/en/lan ... remainder/ If you get stuck post your code and we will take a look.
