I assembled the unit correctly. But when I power it on the sensor turns to the right and stays. It does not automatically rotate 360. Unable to use it for line tracking and obstacle avoidance mode. I have not uploaded any code. It just has the code loaded from the factory.
I hate to break it to you, but this is not an "installation & troubleshooting" issue.
Also, not many of us will necessarily know a great deal about the device you're using, so some details would help others help you.
This is a arduino based smart robot car kit intended for hobbyists. Details can be seen here.
After assembling the unit and powering on, the camera/ultra sonic sensor turns one direction only and stays locked there. It is supposed to do a 360 degree scan for obstacle avoidance. Trying to troubleshoot where the issue is. The wiring all look good. I have not modified any code, so it is running on pre-installed code from the factory.
It seems crazy to me to assemble the whole thing, and only then test it - even crazier to publish a video to suggest that this is a sensible thing to do.
@siparovi he is right you know. That is why I have moved your question here.
I recommend you download the source code for the factory sketch.
Upload the factory sketch to the car. If that fixes the problem it was probably a bad upload at the factory.
If the problem continues with the factory sketch, now you can test the hardware parts using libraries and example sketches (Servo->Sweep, for example). You will need to determine to what pins each device is connected.
Thanks, will try that.
