In this chapter, we saw how we can create some portable speakers, so that we are able to play our favorite music everywhere. Since music changes the mood, an interactive way of understanding the reader's mood and playing specific playlists was added in the last sections. Furthermore, we saw how you can control the volume and the audio of your Linux system through the terminal. Lastly, we mentioned some music and video players necessary for your everyday audio or video interaction with the Raspberry Pi Zero W.

In the next chapter, we will go through developing a small hosting service in our home using only the Pi wireless board.
