Arduino Bluetooth Terminal

The easiest way to visualize Arduino Sensor-Data directly on your Android-Device in REALTIME! The App is able to display the values of up to 6 Sensors simultaneously.

Only required is to load some Code to your Arduino-Board, wire a Bluetooth-Module (like the HC-05) to the Arduino and couple Android-Device and Bluetooth-Module in the System-Preferences.
The App will establish a wireless Bluetooth-Serial-Connection between Arduino and Smartphone.

Requirements:
-Arduino
-Bluetooth-Modul (HC-05, HC-06, ...)

The Bluetooth-Module has to be wired as shown at the labeling of the Module (Caution: HC-05 TX has to be wired to Arduino Pin 10 (RX), HC-05 RX has to be wired to Arduino Pin 11(TX)).
The following Code needs to be uploaded to the Arduino-Board:

Important Notices:
ArduTooth: This Arduino-Code is written for Visualizating measurement data from a microcontroller via Bluetooth.
Before starting this application, the Bluetooth-Modul (HC-05) has to be coupled to the Smartphone.
In the special case of the HC-05 the default PinCode for initiating the Coupling-Process is "1234" or "0000".

Wiring:
GND of HC-05 to GND Arduino, VCC of HC-05 to VCC Arduino,
TX HC-05 to Arduino Pin 10 (RX)
RX HC-05 to Arduino Pin 11 (TX)
