New Arduino Motor Shield R3

Hello to all i just buy a new Arduino Motor Shield R3 From Radio Shack http://arduino.cc/en/Main/ArduinoMotorShieldR3 and i found problems to run a simple step motor ( 4 wires) i can not get to turn the step motor i can not find any sketch or library for this new board i replace the values to work with pin 3 , 11 ,12 and 13 and still dont work

Please help me where i can get info, sketch or pde files

Thank

i replace the values to work with pin 3 , 11 ,12 and 13 and still dont work

You replaced the values in what?

where i can get info, sketch or pde files

Fire up the IDE and start typing. When your done, post your code, if you have problems.

This is the code to be more speciffic

#include <Stepper.h>
/* This Rugged Motor Shield application demonstrates keyboard control

  • of a stepper motor. Assumptions:
    • stepper motor connected to the 2 phases
    • 8V-30V supply connected to Vin (optional, else Arduino Vin is used)
    • Vin jumper is cut (J21) (only required if Vin>15V)
    • FAULT1 and FAULT2 jumpers (J10/J14) installed (optional)
    • LED jumpers (J15, J16, J6, J7) installed (optional)
  • The behavior is as follows:
    • The ‘f’ key sets forward motion
    • The ‘b’ key sets backwards motion
    • The ‘a’ key accelerates rotational speed
    • The ‘d’ key decelerates rotation speed
    • The ‘o’ key increases motor power (PWM higher duty cycle)
    • The ‘m’ key decreases motor power (PWM lower duty cycle)
