Arduino Motor Sheild & DC Motor

I can not find anything on the WEB about using the Arduino Motor Sheild to control a DC Motor. My understanding is that it can control 2 DC Motors. I asume the motor would be connected to either the A or B two screw downs on the blue block. If not correct then how?

After I plug the Arduino Motor Sheild into the Arduino, how do I program the Arduino then.

This might help....

Yes it did help. Thanks. Based on it I was able to get variable speed from the motors. Simplified code follows:

#define DIRA 12 // Direction motor pin
#define DIRB 13 // Direction motor pin
#define PWMA 3 // PWM motor pin
#define PWMB 11 // PWM motor pin
#define BREAKA 9 // Break A
#define BREAKA 1 // Break B
#define CURRENTA A0 // Current Sensing A
#define CURRENTB A1 // Current Sensing B

int PWM_val = 0; // (25% = 64; 50% = 127; 75% = 191; 100% = 255)

void setup()
{
analogReference(EXTERNAL); // Current external ref is 3.3V
// Serial.begin(115600);
Serial.begin(9600);
pinMode(DIRA, OUTPUT);
pinMode(DIRB, OUTPUT);
pinMode(PWMA, OUTPUT);
pinMode(PWMB, OUTPUT);
pinMode(CURRENTA, INPUT);
pinMode(CURRENTB, INPUT);
digitalWrite(CURRENTA, HIGH);
digitalWrite(CURRENTB, HIGH);

analogWrite(PWMA, PWM_val);
analogWrite(PWMB, PWM_val);
digitalWrite(DIRA, HIGH);
digitalWrite(DIRB, HIGH);
delay(5000);
} /* setup */

void loop() {

for (PWM_val = 0; PWM_val <= 255; PWM_val = PWM_val +10)
{
analogWrite(PWMA, PWM_val); // send PWM to motor
analogWrite(PWMB, PWM_val);
Serial.print(“PWM:”); Serial.print(PWM_val); Serial.print("\n");
delay(2000);
} /* for */

} /* loop */
