1. Building Your First Internet of Things App

To help introduce you to the style of this book, your first project will be a very simple application that demonstrates several of the steps you will take when building an Internet of Things application: creating a project, including hardware-specific frameworks, retrieving data, and displaying it. For your first project, you will create an application that logs the user’s location using his phone’s GPS chip and displays it on a map. This app could be used to help him find his car if he has the tendency to forget where it is (like a certain author). Figure 1-1 shows the mock-up, indicating the major user interface (UI) components and the flow of the application. The application you will create will follow the guideline set by this mock-up closely.
