In this chapter, we discovered how to interface our BeagleBone Black to several devices with a different power supply voltage, and how to manage a 1-Wire device and a PWM one. Also, we presented the
Drinks toolkit to realize a web control panel that can be used equally from a PC, smartphone, or tablet.
In the next chapter, we'll see how to realize a weather station that can store its collected data locally, which can not only show them in a nice manner on a web browser, but also can send its data to a Google Docs document!
Simply speaking, we're going to realize a simple Internet-of-Things (IoT) machine.
