To make our Galileo board get the current weather measurements and broadcast it to Twitter, we have performed the following steps:

First, we organized and structured our web app with Express. Node.js was responsible for the data and measurement, while Jade was used to build the interface. We also use jQuery to handle the interface, and Bootstrap CSS to give a better look to the app.

Then, we learned to add an online forecast to the app. Finally, we learned how to interface our app with Twitter so we could tweet the data on our twitter accounts.

In the next chapter, we will continue with a more complex Internet of Things application. We will make the Galileo board into an online data-logging platform, so that we can access and plot the data from any web browser.
