BT Robot Controller uses UART serial communication protocol to transmit data wirelessly to your robotic rover over a bluetooth connection.

The app features 3 modes:

1. Remote Controller

The Remote Controller has 5 buttons respectively for Forward, Backward, Left, Right and Stop. When a button is pressed, the app transmits a specific character corresponding to that button using bluetooth serial (UART) communication protocol.

2. Voice Controller

The Voice Controller has a "Command" button. It understands 5 commands, viz. Forward, Backward, Left, Right and Stop. When a command is recognized, the app transmits a specific character corresponding to that command using bluetooth serial (UART) communication protocol.

3. Accelerometer Controller

The Accelerometer Controller senses the orientation of your device and accordingly drives the robotic rover Forward, Backward, Left, Right or Stops it. Depending upon your device's orientation, the app transmits a specific character using bluetooth serial (UART) communication protocol.

The default characters to be sent to the robot representing each function are as follows:

w: Forward
s: Backward
a: Left
d: Right
x: Stop

Users can also set custom characters from the "Configuration" menu. However, note that once the app restarts, the defaults will be restored.

FEATURES:

1. Tested using HC-05 Bluetooth Module and Arduino UNO.

2. Three controllers in a single app - Remote Controller, Voice Controller, Accelerometer Controller.

3. "Configuration" menu for transmitting custom characters to the robot.

4. "Connect" and "Disconnect" buttons to quickly switch between connections without closing the app.

5. Multi-page systematic user interface for convenient usage.

6. Completely FREE! No Ads!

Think these features are limited?

You can use another Android App developed by us to send and receive custom commands over Bluetooth. Its called "BT Terminal" and is available at: https://play.google.com/store/apps/details?id=appinventor.ai_samakbrothers.BT_Terminal
