In this project we’ll show you how we added NeoPixels to our drone to make it look like a it has a tractor beam. 

This is really simple project just in time for Halloween or even lighting effects for a video.

All you’ll need to build this project is an Adafruit Trinket and a 24 NeoPixel ring.

We designed and 3D printed a custom mount to attach to the landing gear of a DJI Phantom 4. The Phantom 4 is able to power the trinket through the USB port on the side and the 3d printed clips holds all of the parts.

Prerequisite Guides

We suggest walking through the following guides to get a better understanding of the components and Arduino IDE. We also have great tutorials on learning how to solder.
