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
of Bluetooth Smart Car better.
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.
