Hello, I believe I have explained every line and what they do. so I would suggest watching the video 2 or 3 times until you understand it. Just see which line in the code makes the motor to run make copy of the same line in the line below it and change the value to make the other motor rurn. or may be watch this video kzread.info/dash/bejne/qaJpppmjYdzIqLw.html and learn which line controls a motor.

Hi, this should work. just identify the pins. check or test be lifting the car and turning it ON. using whatever controller you have try going forward and se which wheels rotate. then turn left and check which motor rotate and the same for right turn. I am not sure if the car has servo to physically turns the wheel or just by controlling the each motor it rotates. My point is to see if 4 motor is used when running the car or just two sets run together. this can be checked to see if two L298N is used or 1. here an one of 4 videos on a smart car kzread.info/dash/bejne/fHibsbuEn8LggZs.html using L298N.

It is my understanding that the L298N requires a 5 volt signal on the logic inputs while the ESP32's output is 3.3V. Would it be more reliable to use a logic level shifter to take the 3.3V up to 5V? Just curious. Thanks again for the tutorial!
