      Hi Siripong,

      well observed – you need to cut the “Vin Connect” jumper on the motor shield, as described here (https://www.arduino.cc/en/Main/ArduinoMotorShieldR3):

      “To avoid possible damage to the Arduino board on which the shield is mounted, we reccomend using an external power supply that provides a voltage between 7 and 12V. If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the “Vin Connect” jumper placed on the back side of the shield. The absolute limit for the Vin at the screw terminals is 18V.”
