step motor 28BYJ-48 use 1 coil to rotate code example

Example: step motor 28BYJ-48 use 1 coil to rotate

1.	#include <Stepper.h>
2.	
3.	#define STEPS 2038 // the number of steps in one revolution of your motor (28BYJ-48)
4.	
5.	Stepper stepper(STEPS, 8, 10, 9, 11);
6.	
7.	void setup() {
8.	// nothing to do
9.	}
10.	
11.	void loop() {
12.	stepper.setSpeed(1); // 1 rpm
13.	stepper.step(2038); // do 2038 steps -- corresponds to one revolution in one minute
14.	delay(1000); // wait for one second
15.	stepper.setSpeed(6); // 6 rpm
16.	stepper.step(-2038); // do 2038 steps in the other direction with faster speed -- corresponds to one revolution in 10 seconds
