Before we commence our chapter by building circuits and looking at code, let's take a moment to understand what our IoTree will do and how we will be building it. The tree pictured in Figure 14.1 is representative of what you could create after completing this chapter:

Now, I'll need to let you know up front that we're only covering the electronics and programming of the IoTree. You'll need to apply your initiative and bring your maker skills to the table to build the tree and bring it to life. I suggest using a small table-top Christmas tree since part of our build involves a servo to shake the tree. Our hobby-grade servo is powerful enough to shake a small tree; however, it's unlikely that it could shake a full-size Christmas tree (you'll need to research and get a more powerful servo if you aspire to upgrade our build to a larger tree – and please send me...
