Can any one please help me to convert this code from motorsheild v1 to v2

This is the code (BLUETOOTH_CAR.ino - Google Drive) please help me.

You should post code by using code-tags
There is an automatic function for doing this in the Arduino-IDE
just three steps

  1. press Ctrl-T for autoformatting your code
  2. do a rightclick with the mouse and choose "copy for forum"
  3. paste clipboard into write-window of a posting

You are welcome on this forum! You are working on an informatic project and what is most needed in an informatic project is information imagine: do the other users here in the forum have a clear picture of what you are trying to do?

To speed up finishing your project you should invest some time into writing additional information I'm 100% sure that this WILL speed up finishing your project.

So please go through this checklist and if you find an item you haven't posted yet post it

  • did you write which exact type of microcontroller you are using?
  • description of your programming skills and knowledge
  • description of your knowledge about electronics
  • description of the functionality you want to have written in normal works avoiding programming terms
  • do you have an oscilloscope? Yes / No
  • do you have a digital multimeter (DMM) Yes / No)
  • your age
  • did you post your complete sketch?
  • if relevant did you post a link to a datasheet of each component you are using?
  • if relevant did you post a handdrawn schematic or your wiring?
  • if you got a compiler-error. Did you post the complete compiler-output into a code-section?

If you don't post all this information because you want a "quick answer" to your detail problem It is very likely to turn out that all that happens is having mutliple waiting-times with mutliple asking back for details until the other users do have a clear picture of what you want to do.

This compiles without error or warning. I don't know if it works on your hardware:

//Arduino Bluetooth Controlled Car
//Before uploading the code you have to install the necessary library
//Note - Disconnect the Bluetooth Module before hiting the upload button otherwise you'll get compilation error message.
//AFMotor Library https://learn.adafruit.com/adafruit-motor-shield/library-install 
//After downloading the library open Arduino IDE >> go to sketch >> Include Libray >> ADD. ZIP Libray >> Select the downloaded 
//ZIP File >> Open it >> Done
//Now You Can Upload the Code without any problem but make sure the bt module isn't connected with Arduino while uploading code

#include <Adafruit_MotorShield.h>

// Create the motor shield object with the default I2C address

// Or, create it with a different I2C address (say for stacking)
// Adafruit_MotorShield AFMS = Adafruit_MotorShield(0x61); 

// Get pointer to the four motor ports
Adafruit_DCMotor *motor1 = AFMS.getMotor(1);
Adafruit_DCMotor *motor2 = AFMS.getMotor(2);

thanks you are my best freind thhanks it compiled thank you so much i was go so streesed with it thank you so much
