# Circuit Playground & Fiber Optics ## Intro & Setup https://youtu.be/tI11D4ws83g Circuit Playground is a really fun, really easy to use micro controller that is a great way to add sensors and interactivity to your project without a whole lot of fuss and soldering. It's got a built in motion sensor, a sound sensor, a light sensor, and a temperature sensor, as well as a built in speaker and 10 neopixels, ready to use right out of the box.  I'm just starting to explore the fun things this board can do. Today we're going to play with the onboard neopixels and add fiber optics or light pipe to make your project dance and shine. ![](https://cdn-learn.adafruit.com/assets/assets/000/039/470/medium800/led_pixels_fiber_optic_circuit_playground.jpg?1487557076) # Materials - Circuit Playground - Battery (liPoly, AAA or USB)  - optional - Light Pipe or Fiber Optics - Hot Glue or Superglue ## Tools - 3d Printer - Sharp scissors or snips Note: If you don't have a 3d Printer, you can easily just order the case from [Shapeways](https://www.shapeways.com/product/K5Q5EXPEF/circuit-playground-light-pipe).   # Before You Start If this is your first foray into the world of arduino-based microcontrollers, you'll need to install some software first.  Head over to the [Circuit Playground Lesson 0 guide](../../../circuit-playground-lesson-number-0/install-software-linux?view=all#intro) for detailed installation and setup instructions.   You'll only need to do all this once, so be a little patient if it seems like a lot!  This is actually the hardest part. - [Next Page](https://learn.adafruit.com/circuit-playground-light-pod/code.md) ## Featured Products ### Circuit Playground Classic [Circuit Playground Classic](https://www.adafruit.com/product/3000) Would you like to learn electronics, with an all-in-one board that has sensors and LEDs built in? **Circuit Playground** is here - and it's the best way to practice programming on real hardware with no soldering or sewing required!
