In this chapter, you learned how to control your Arduino and Raspberry Pi Zero from a smartphone using Android Studio and APP inventor, via Bluetooth and Ethernet communication. We also looked at several projects such as controlling a motor, controlling a relay module, and reading humidity and temperature. For future projects you can now control and monitor anything you want in any area of the application you want.

In the next chapter, we will integrate everything from the previous chapters and put it all together to integrate all the knowledge applying all the things.
