Smart Car v.2 remote control project moves forward but not backward

July 29 - I downloaded the code as provided and then added the Speed Calibration. In both cases, the car moved forward but not backward. The earlier Smart Car model has a different motor driver, and it moves backward, but the newer motor driver does not. I tried different pins for the IR receiver, in case it was a timing issue, but still no go. Any suggestions?

  1. Please follow the tutorial link:
    Remote Control — SunFounder PiCar-V documentation
    Run the server:
    cd ~/SunFounder_PiCar-V/remote_control
    python3 manage.py migrate
    sudo . /start
    To enter the operation interface, click the full screen again to return to the title bar, and then click the Settings button at the top right corner of the page to enter the calibration page. (As shown in the picture) When you enter this page, the car

    will move forward; if it does not move forward, please click the “Left/Right” button in the rear wheel calibration to adjust the angle of the wheels.
  2. Please provide us with a video of the problem so that we can analyze and solve the problem.
