Arduino Voice Control

Using this app, one can send and receive data from devices such as an Ultrasonic sensor connected to the Arduino using Bluetooth.

For connecting the Arduino connected device to the mobile phone using Bluetooth, an HC-05 module was used.
The ultrasonic sensor was placed at the front of a remote controlled manual robot (car).

Once connected, the ultrasonic sensor will transmit the distance of the nearest object and this will be displayed on the mobile phone in our app.

The Arduino was programmed for a list of commands to be recognized such as - "Forward", "Back", "Left", "Right" and "Stop".

The app uses Android's built-in speech recognition software for performing speech recognition and passes this text to the Arduino which then performs the required command.

The ultrasonic sensor sends the nearest object's distance to the Arduino, which then sends it to the app using the HC-05 Bluetooth module.
