Welcome to our final chapter! We will round out this book by pulling together various topics and ideas from earlier chapters to build a multifaceted IoT program. Specifically, we will be building an internet-controllable Christmas tree, an IoTree, if you don't mind the pun!

We will then revisit and adapt our learning about RESTful APIs and MQTT to create two ways in which we can control the lighting and servo over a network or the internet.
