	/*
	SEEED Studio Stepper Motor Control - one revolution

	Adapts the Stepper example for use with the SEEED STUDIO motor shield.
	This program drives a unipolar or bipolar stepper motor
	by using the included Stepper library of the Arduino.
	The motor is attached to the Seeed Studio motor shield and an Arduino.

	The digital pins 8,11,12,13 drive the L298N and are used when creating the stepper object
	Digital pins 9 and 10 must be high to enable the chip.

	#include <Servo.h> // Use Servo library, included with IDE
	Servo myServo; // Create Servo object to control the servo

	void setup() {
	myServo.attach(9); // Servo is connected to digital pin 9
	}

	void loop() {
	myServo.write(0); // Rotate servo counter clockwise
	delay(2000); // Wait 2 seconds
