Stepper

Stepper motor library for arduino

Setup a stepper motor with its constructor (this should be done in setup()):

Stepper(int pins[], byte steps[], float stepsPerRotation, float rotationsPerMinute, float distancePerRotation, byte direction);

eg

Stepper stepperX = Stepper((int[]){4, 2, 3, 4, 5}, (byte[]){4, B1010, B0110, B0101, B1001}, 200, 350, 5, CLOCKWISE);

Array Inputs

The first element in each array arguments on construction should represent the number of elements in that array. eg "int pins[]{4, 2, 3, 4, 5}" means a motor is connected to 4 pins with pin numbers (2,3,4,5)

Once a Stepper is constructed, you can call any of the step functions:

step(int steps);
rotate(float rotations);
rotateByDegrees(float degrees);
move(float distance);

Ensure that the run() method is called

The run method must then be called from anywhere within your loop() function - Note if this is not called often enough, there may be problems with step timing.

void loop() {
  stepperX.run();
}

Default Values

Argument	Default Value
pins	N/A
steps	{8, B1000, B1100, B0100, B0110, B0010, B0011, B0001, B1001}
stepsPerRotation	4075.7728395
rotationsPerMinute	12
distancePerRotation	200
direction	CLOCKWISE

These defaults are designed for the 28BYJ-48 motor.
