Introduction

Make beautiful 3d printed glowing flowers to string around your room or your back yard.  Use the Circuit Playground Express' onboard sensors to make the lights react to their environment:  when it gets dark outside the lights come on automatically and shine bright, and when it's light out they will turn themselves quietly off.  

This guide will cover modeling the flowers in Fusion360, connecting the light strand to a Circuit Playground Express, and creating animations and reactivity with the MakeCode editor.

There's so much you can do with the Circuit Playground Express. This project is a jumping-off place to creating your own designs and making the lights do whatever you can dream up.
