Arduino with bluetooth shield

Using Arduino Installation & Troubleshooting
#1

I am new to Arduino…
I want it simple: build a car, wich one you can control with bluetooth.

I have:

  • Arduino Uno
  • Bluetooth shield
  • Adafruit motor shield
  • 4WD platform (4 DC motors)

I’ve made a code to run te motors, when sending an “r” trough a bluetooth terminal on my Android phone.

This is the code (wich one not works):

/* Upload this sketch into Crowduino and press reset*/
#include <AFMotor.h> 
#include <SoftwareSerial.h>   //Software Serial Port
#define RxD 6
#define TxD 7

SoftwareSerial blueToothSerial(RxD,TxD);
AF_DCMotor motor1(1); 

void setup() 
{ 
  Serial.begin(9600);
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
  setupBlueToothConnection(); 
} 
 
void loop() 
{     
  char recvChar;
  while(1){
    if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
      recvChar = blueToothSerial.read();
      Serial.print(recvChar);
    }    
    
    if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other applications here
      recvChar  = Serial.read();
        if(recvChar=='r'){
          motor1.setSpeed(1000);
  motor1.run(BACKWARD);
        }
    }
  }
} 
 
void setupBlueToothConnection()
{
  blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
  blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
  blueToothSerial.print("\r\n+STNA=CrowBTSlave\r\n"); //set the bluetooth name as "CrowBTSlave"
  blueToothSerial.print("\r\n+STPIN=0000\r\n");//Set SLAVE pincode"0000"
  blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
  blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
  delay(2000); // This delay is required.
  blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable 
  Serial.println("The slave bluetooth is inquirable!");
  delay(2000); // This delay is required.
  blueToothSerial.flush();
}
