The Arduino Based Voice Controlled Robotic Car is a smart robotic vehicle that can be controlled using voice commands sent from an Android smartphone via Bluetooth. The system converts spoken commands into actions such as moving forward, backward, turning left, turning right, and stopping. This project demonstrates the practical application of embedded systems, wireless communication, and automation.

OBJECTIVES

• Design and develop a voice-controlled robotic car.

• Implement wireless communication using a Bluetooth module.

• Control DC motors using an Arduino Uno and motor driver.

• Demonstrate hands-free operation through voice commands.
