An Android application listens to an Arduino via Bluetooth LE to display live data with a graph view for historical plots. Analog sensors are connected to the Arduino's serial pins to continuously read data. The Arduino reads the data and outputs the values to an HM-10. While the HM-10 broadcasts the values, the Android application listens to the HM-10 via its GATT service profile.

1. Clone the repository at this link.
2. Upload the Arduino script to the Arduino through the Arduino IDE
3. Open the Android application with Android Studio

/Arduino-Sensor contains the Arduino (C++) script.

/Android-App contains the Android Studio project files for the Android application.
