You can build a Tron-inspired prop using NeoPixel LEDs and CircuitPython.

Powered by the Adafruit Feather and Prop-Maker FeatherWing, this Tron disc is fully 3D printed.

With the power of neodymium magnets, this disc can actually attach to your back!

Using a mobile device and the Bluefruit app, you can change the color of the LEDs, so it's easy to switch your team color.

The Prop-Maker FeatherWing and Feather Bluefruit are the perfect pair for making advanced props with motion-activated lights and sounds that can be controlled wirelessly from your phone or watch. 

The code is written in CircuitPython, so it’s easy to modify to fit just about any prop with lights and sounds.

It uses Bluetooth (BLE) and the LED animation library to trigger lighting effects with the Prop-Maker’s on-board accelerometer.
