Controlling a Roomba Robot with Arduino and Android device

As one of Instructables Robotics Contest 2016’s winners, I received as a prize an iRobot Roomba Create2. It is a great and very affordable platform for robotics development, costing around US$200. Create 2 allows for a variety of programming methods. As a start, I used it with an Arduino and an Android APP to move the robot around. In this first tutorial, I will explore how to connect the Arduino with the Roomba via serial port and how to command its motors, LEDS and sound. On a future projects, I will explore its sensors and also use a Raspberry Pi to connect the Roomba with internet.”
