This is a simplified version of any other voice control robot, No complex coding easy to understand coding with easy algorithm.
The app is developed in such a way that it convert the voice command to text and transfer the text to the connected Bluetooth device.
The bluetooth connected on the Arduino board receives text from the Android app as characters and stored them as string to the assigned String.
There are words pre-programmed (forward, reverse, right , left and stop) to the arduino , whenever the received text matches with the pre-programmed words ,the arduino executes the command that assigned to the words.
Arduino can connect to Laptop to monitor serial communication and check the working process and the words received by the Bluetooth.
