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 10 Sensors simultaneously (in Receiver-Mode). With the new Terminal-Mode you even can send data to your Arduino. The responds will also be shown in the App. 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. For a How-To click on the link: http://www.instructables.com/id/How-to-Receive-Arduino-Sensor-Data-on-Your-Android/ 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)).
