Thank you very much Flamingo.

一组应该是：

I just remove the led connected to pin 13 onboard. This led is connected to pin 13 via a 470 ohm resistor. And when this led lit up, the voltage on pin 13 will be set to about 2V by the led. I'm using the Arduino NG. And they solved this problem by removing the led in later NG version. I solved the problem now.

And how you power up your board with motor? By external 12V power? I didn’t meet this problem, how about motor 1? And how you power up your board with motor? By external 12V power?

When I apply a 'HIGH' to pin 13, the voltage of pin 13 will be about 3.6V and suddenly changed to 1.9V as the LED (connected to pin 13 on board) lit up. And therefore the motor 2 cannot operator, i.e. not moving. Do you have any idea ? Thanks. I have a question.
