In this chapter, we managed to create our very own mobile robot together with a companion Android application that we can use to control our robot.

We achieved this step by step by setting up an Arduino-enabled robot and coding the companion Android application. It uses the BLE software and hardware of an Android physical device running on Android 4.3 or higher.

In the final chapter, we will consider a more direct form of user interaction, by measuring our pulse rate using Android, Arduino, and a specific sensor.
