The necklace consists of a series of Neopixel LED strips, housed within a tidy 3D printed housing made with flexible filament. A dovetail joint makes putting on and removing the necklace a cinch.

Almost every project I have made over the last two decades has included some form of LED lights in ... was my main draw to the Neopixel; Adafruit has written a custom Arduino library and provided ...

I used two strings of lights for this project—an Adafruit NeoPixel ... sure the LED string will correctly fit the pattern you drew. Start with the end of the string so the Arduino ends up ...

The build relies on an Arduino Pro Mini to run the show ... The individual triangles are each lit by a NeoPixel LED, which are both addressable and capable of lighting up in RGB colors.

Makers and electronic enthusiasts looking to add light and colour to the next project may be interested in the arrival of a new NeoPixel RGB Neon-like LED Flex Strip to the Adafruit online store.
