Simulated Glowy Physics!
These LEDs interact with motion and looks like they’re affect by gravity. An Adafruit LED matrix displays the LEDs as little grains of sand which are driven by sampling an accelerometer with an Adafruit Feather.
The code, written by Phillip Burgess, simulates physics by calculating collisions and terminal velocity.
We designed 3d printed enclosures to take advantage of sensor readings by allowing it teeter totter as well as a gimbal to create interesting simulations.
Create interactive simulated grains of sand! In this project we’ll show you how to build an LED physics toy. These LEDs interact with motion and looks like they’re affect by gravity.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
