                 Integrating the System


                 ●  Steps:

                     Step 1   Connect the circuit.
                     Step 1   Open the Android App and pair it with the HC-05 module.

                     Step 1   Press control buttons and observe robot movement.

                                 Scan the QR code and refer to the video for understanding the assembly

                 Testing and Debugging

                 ●  If the car does not move, check motor driver wiring.
                 ●  If Bluetooth fails to connect, re-pair the module.

                 ●  If the car moves in the wrong direction, swap motor driver pins.



                 Your Arduino robot car now moves in response to wireless commands, bridging hardware and
                 code for a dynamic experience. In the next lesson, we’ll explore how artificial intelligence can
                 add an entirely new dimension to your projects. Imagine a face-recognition mood lamp that

                 detects a person’s expression and changes color to match their mood—this is just one example
                 of how AI can bring your robotics creations to life in surprising, interactive ways. Stay tuned for a
                 deep dive into the fascinating world of AI-powered electronics!


                   Remember:  A  mobile robot  transforms  simple circuits  into  interactive  machines. With
                   careful wiring, a suitable chassis, and a motor driver, you’ve added motion to your projects,
                   opening doors to more creative and dynamic robotics applications.
