L298N, HC-05 Simple Bluetooth remote car not running in Arduino

Question

Arduino board type used in this session is Arduino Uno R3 DIP/SMD CH340

Below is the description of wiring and code in Arduino to assemble a Bluetooth RC car using android smartphone:

1. Tested the motor dc result both of wheel works (can spin forward and or backward). power direct from the battery.
2. Tested HC-05 bluetooth moduled. The phone can paired the bluetooth module.
3. Tested out1 out2 out3 and out4 on L298N using direct power from the battery the wheel spinning (forward and or backward).
4. The code for the Bluetooth rc simple car used below as described.

The car failed to move (forward, backward, turn left/right). how to make the motor dc and or the motor stepper works remotely. thank you

#include SoftwareSerial mySerial(12, 13); // RX, TX #define m1 3 #define m2 5 #define m3 9 #define m4 10

int data=0,kec=0;
boolean forward=true;


int fast[11]={0,80,100,120,140,160,180,200,220,240,255};

void setup()
{
  pinMode(m1,OUTPUT);
  pinMode(m2,OUTPUT);
  pinMode(m3,OUTPUT);
  pinMode(m4,OUTPUT);

  mySerial.begin(9600);
 }

void motorOut(unsigned char lpwm, unsigned char rpwm, boolean arrow){
   if(arrow==false){
      digitalWrite(m3,HIGH);
      digitalWrite(m1,LOW);
      analogWrite(m4,255-lpwm);
      analogWrite(m2,rpwm);

     digitalWrite(m1,HIGH);

}

void loop(){
  if(mySerial.available()>0){
    data=mySerial.read();
    if (data =='0') { kec=0;}
      else if (data =='1') { kec=1;}
        else if (data =='2') { kec=2;}
          else if (data =='3') { kec=3;}

                      else if (data =='q') {kec=10;}

  //S= Stop
 if (data == 'S')
 { motorOut(0,0,false); }

//F=Forward
if (data=='F')
{ motorOut(fast[kec],fast[kec],true); }

//I=turn right forward
if (data=='I')
{ motorOut(fast[kec],((fast[kec])/2),true);}

//G=turn left forward
if (data=='G')
{ motorOut(((fast[kec])/2),fast[kec],true); }

//R=turn right
if(data=='R')
{ motorOut(fast[kec],0,true); }

//L=turn left
if(data=='L')
{ motorOut(0,fast[kec],true); }

//B=back
if(data=='B')
{ motorOut(fast[kec],fast[kec],false); }

//H=turn left back
 if (data=='H')
   { motorOut(((fast[kec])/2),fast[kec],false); }

//turn right back
   if (data=='J')
    { motorOut(fast[kec],((fast[kec])/2),false); }
  }
}

Answer 1

sorry for my careless. finaly its works....wrong pin assign the main problem....should be IN1, IN2, IN4 and IN3 not IN1, IN2, IN3 and IN4. thank you for all hands for help before
