This chapter introduced you to Android Things and how it works. We installed Android Things on Raspberry Pi 3 and Intel Edison. This was a necessary step so that we have a development board where we can test our next Android Things IoT projects. We developed and tested our first Android Things app that interacts with external peripherals. Now, you are ready to start developing amazing IoT projects using Android Things SDK.
In the next chapter, we will build an alarm system. We will use a PIR sensor with Android Things to detect motion. Moreover, you will explore how to use GPIO pins to communicate with the external world.
