Hello,
I have an Arduino UNO R3 and Motor Shield. I want to control a dc motor via motor shield.
I am new at programming.
Are there any control program example for me ? Thank you.

I found this code for using one DC motor but the motor did not work. I got this error : avrdude: stk500_getsync(): not in sync: resp=0x00
How can I fix this code ?
void setup() {
//Setup Channel A
pinMode(12, OUTPUT); //Initiates Motor Channel A pin
pinMode(9, OUTPUT); //Initiates Brake Channel A pin
}
void loop(){
//forward @ full speed
digitalWrite(12, HIGH); //Establishes forward direction of Channel A
digitalWrite(9, LOW); //Disengage the Brake for Channel A
analogWrite(3, 128); //Spins the motor on Channel A at full speed
delay(3000);
digitalWrite(9, HIGH); //Eengage the Brake for Channel A
delay(1000);
//backward @ half speed
digitalWrite(12, LOW); //Establishes backward direction of Channel A
digitalWrite(9, LOW); //Disengage the Brake for Channel A
analogWrite(3, 123); //Spins the motor on Channel A at half speed
delay(3000);
digitalWrite(9, HIGH); //Eengage the Brake for Channel A
delay(1000);
There's nothing wrong with the code (well, nothing syntactically wrong) - that's an upload error; did you select and connect the correct board?
did you select and connect the correct board?
And, did you make sure that there is nothing connected to pins 0 and 1 (directly or via any shield)?
Yes, I selected the correct board (Arduino UNO R3).

There is nothing connected any pins on shield. Just USB and motor connections on shield (A+ A-) are connected
Is there any idea ? :~
Is there any idea ?
I have a couple. First, you might try telling us, via a link, just which shield you have.
Second, you might try removing the shield while uploading the sketch.
