Summary

Let's summarize what we did in this chapter.

First, we built two Wi-Fi Arduino modules; one for the LED module and the other one for the sensor. Alternatively, you can also replace these Wi-Fi modules with other Galileo boards with Wi-Fi modules, or with Intel Edison boards that have built-in Wi-Fi.

Then, we tested them by pinging the boards and getting their IP addresses.

Finally, we integrated everything into a single interface with the help of the Node.js, a Jade interface, and lastly, JavaScript.

In the next chapter, we will use everything you learned so far for a different and more exciting application—building a mobile robot! You'll learn how to transform the Galileo board into a robot's brain.
