The shield typically includes two 3-pin headers for Servos.

void setup() Serial.begin(9600);

If you have the specific HW-130 document (or a link to it), I can check for version-specific errors.

You are drawing more than 600mA of continuous current. Reduce the load on the motor, lower the voltage, or glue small aluminum heatsinks onto the top of the two 16-pin L293D ICs.

Up to 4 bidirectional DC motors (with 8-bit speed resolution)

Would you like a , a library usage guide , or a stepper motor example for this shield?
