# Simple LED Unicorn Horn ## Overview https://www.youtube.com/watch?v=iR1bdFlpZ10 ![](https://cdn-learn.adafruit.com/assets/assets/000/035/760/medium800/leds_hero-2.jpg?1473959441) ## 3D Printed Unicorn Horn It's unicorn season! Last year we 3D printed a unicorn horn, this year we made it simpler! Redesigned in Fusion 360, this unicorn horn features a spiral design and tabs for sewing onto garments such as hats, hoodies and other headware. This unicorn horn lights up and features a UV Purple LED, so it's magical as it is whimsical. ## Want More Magic/Colors? Want a more advanced unicorn horn? Check out our first Unicorn horn project! - [NeoPixel Unicorn Horn using GEMMA](../../../3d-printed-unicorn-horn) ![](https://cdn-learn.adafruit.com/assets/assets/000/035/759/medium800/leds_hero-1.jpg?1473959416) ## Great For Beginners This project is as simple as it gets! There's no micro-controller or programming required. The circuit is just an LED, a JST breakout with on/off switch and a battery - That's it! If this is your first time using LEDs or soldering wires, this is the project for you! ![](https://cdn-learn.adafruit.com/assets/assets/000/035/761/medium800/leds_parts.jpg?1473959548) ## Parts & Tools We have all of the tools and parts you'll need for this project in the shop.
