Lesson 6 - xyzen/CS490 GitHub Wiki
In this lesson, we will use an Android app developed with MIT App Inventor to interface with a Bluetooth device connected to the Arduino. We will use the interface to transmit data between the Arduino and the Android. The data received by the Arduino will be a simple flag used to turn an LED on and off, and the data received by the Android will be ultrasonic sensor data used to turn text in the app red, if an object is detected within 20cm, or green, if one is not.
