Issues with Neopixel Jewel

Projects General Guidance
1

Hi all,
I'm a beginner who's dealing with the Jewel, a specific kind of Neopixel led, and working with this sketch in particular (link Arduino Code | Neopixel Jewel 10 Minute Necklace | Adafruit Learning System).

The problem is, when I load it that's the message I receive "done in 0.013 seconds
CPU reset.", and nothing else happens.

Any ideas?
Do you eventually know some tutorials that are focused on Jewel Neopixels?
