Need help programming motor movement from PS3 controller inputs

I have put together a camera slider that uses a brushed DC motor. It is driven by Arduino Uno and the SeeedStudio Motor Shield (V1.2). I also have a USB shield sandwiched between the Motor Shield and the Arduino. It accepts inputs from the PS3 controller.

I am currently able to receive and view commands from the PS3 controller on my serial monitor. So I know that the PS3 Bluetooth library I have works. What I really need help with is how to take the data from the PS3 controller and move my motor. Forgive the ignorance, but I am brand new to this. Especially the C++. I have had a lot of fun with the basic stamp in the past, but this is a whole new ballgame. Any help is appreciated.

My goal at this early stage is to at least be able to make the camera slide left/right with the L1/L2 PS3 buttons respectively.

I have included picture of my setup as well as the code I am currently using to no avail. I have also included an annotated screenshot of the code to help underscore my problem.

Here’s the code:

#include <PS3BT.h>
USB Usb;
BTD Btd(&Usb); // You have to create the Bluetooth Dongle instance like so
/* You can create the instance of the class in two ways */
PS3BT PS3(&Btd); // This will just create the instance
//PS3BT PS3(&Btd,0x00,0x15,0x83,0x3D,0x0A,0x57); // This will also store the bluetooth address - this can be obtained from the dongle when running the sketch

boolean printTemperature;
boolean printAngle;
int pinI1=8;//define I1 interface
int pinI2=11;//define I2 interface 
int speedpinA=9;//enable motor A
int pinI3=12;//define I3 interface 
int pinI4=13;//define I4 interface 
int speedpinB=10;//enable motor B
int spead =127;//define the spead of motor

void setup() {
  Serial.begin(115200);

  pinMode(speedpinA,OUTPUT);
  pinMode(pinI3,OUTPUT);
  pinMode(pinI4,OUTPUT);

}

void right()//
{
     analogWrite(speedpinA,spead);//input a simulation value to set the speed
     analogWrite(speedpinB,spead);
     digitalWrite(pinI4,LOW);//turn DC Motor B move anticlockwise
     digitalWrite(pinI3,HIGH);
     digitalWrite(pinI2,LOW);//turn DC Motor A move clockwise
     digitalWrite(pinI1,HIGH);
}

void left()//
{
     analogWrite(speedpinA,spead);//input a simulation value to set the speed
     analogWrite(speedpinB,spead);
     digitalWrite(pinI4,HIGH);//turn DC Motor B move clockwise
     digitalWrite(pinI3,LOW);
     digitalWrite(pinI2,HIGH);//turn DC Motor A move clockwise
     digitalWrite(pinI1,LOW);
}

void stop()//
{
     digitalWrite(speedpinA,LOW);// Unenble the pin, to stop the motor. this should be done to avid damaging the motor. 
     digitalWrite(speedpinB,LOW);
     delay(1000);
 
}

I've got the same issue with the same setup. did you ever figure it out?
