Hi,. ...

i can't fined the program of Motor Shield R3 in arduino-1.0.6 ???
i want him to move the libraries pleas i want help ?

Have you seen this:-

You do not need a library to drive this, you just put the appropriate pins high or low.

i with u .... but this error i don't know why show ???

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

No, no one can know until you post your code.

and this is program

No you do not post code like that, it comes out looking like this:-

void setup() 
{ † † † 
†Serial.begin(9600); †//Set the baud rate to that of your Bluetooth module.
†pinMode(pinfrontLights , OUTPUT);
†pinMode(pinbackLights , OUTPUT);
}

void loop(){
†if(Serial.available() > 0){ 
† †timer1 = millis(); † 
† †prevCommand = command;
† †command = Serial.read(); 
† †//Change pin mode only if new command is different from previous. † 
† †if(command!=prevCommand){
† † †//Serial.println(command);
† † †switch(command){
† † †case 'F': †

That will never compile.

Take you .pde file and zip it up and then attache it.

this i write before the program

Sorry no idea what that means.

Just use the pins to control the motor. Here is an example of initialising the motor's pins.

// these are the pins connected to the Arduino Motor Shield:
const int pwmA = 3;
const int brakeA = 9;
const int dirA = 12;
const int pwmB = 11;
const int brakeB = 8;
const int dirB = 13;
/*
Initialize the stepper library using the direction pins (dirA and dirB)
to control the motor shield. 
*/

void setup () {
// set up all of the pins of the motor shield as outputs:
pinMode(brakeA, OUTPUT);
pinMode(dirA, OUTPUT);
pinMode(brakeB, OUTPUT);
pinMode(dirB, OUTPUT);
// set the brake pins LOW to turn them off:
digitalWrite(brakeA, LOW);
digitalWrite(brakeB, LOW);
}

When you want the motor to move, remove the break and do an analogWrite to the pwm pin for the motor.

Hi everyone.

I have a problem with the arduino motor shield rev3.

I connected it to an Arduino UNO without stacking it, I use cables from the outputs. I did this because I need to control 6 motors and I have 3 arduino motor shields, if I stack all of them they will not work.

I am using 9v batteries, one to power on the UNO and another for the motor shield.

The problem I have is that motor shield output A is running slower than output B, but it only happens in the forward direction, in backward direction both outputs speeds is the same.

Any suggestion?

Thanks
