Introduction

Turn yourself or someone you love into a magical animatronic rainbow unicorn.  

The little girl in your life will very likely refuse to ever take this hat off.  (But you can wear it yourself while she's sleeping. We won't tell anyone).  

A joystick in the pocket controls servos inside the ears, and the Circuit Playground's onboard LEDs animate the magical glowing rainbow unicorn horn.  

We've kept this project fairly simple -- it's a great first step into the world of robotics and servos.  This technique will work on any animal hat with attached ears, so if your inner animal is a panda or a fox or some other critter, go nuts.  The world is your animatronic playground.
