Summary
In this chapter, we built a simple weather station using Arduino and Android. We attached several sensors to our Arduino board, along with a Bluetooth Low Energy module. We also built the corresponding Android app so that we can access all the data measured by the Arduino board just by tapping on a button of the phone.
In the next chapter, we will use a different technology to interact with an Arduino board via Android: Wi-Fi. We will build a smart power switch, to control an electrical device remotely, and also to measure the device power consumption via Wi-Fi.
