New try for the first time, the inside of the code is ready, as long as oneself to make circuit, print out the car body can, like recognition and automatic follow algorithm is written in a mobile phone app apk, call phone camera sensors, direct download, and use it every time you fixed your mobile phone in the car and then run the app, then the arduino PWM output, the arduino output L298N control motor,
But my car can identify the portrait, and then straight to follow, but not as the target right corner (occasionally is okay, turn the function can be implemented, but not very sensitive, is often turned in the wrong direction), because there is no modified code so should be no problem, I don't know why will appear this kind of circumstance, everyone is according to the steps as if directly can be successful, would you please tell me what the possible reasons of this?
