Stepper Motor Constant Speed

// ConstantSpeed.pde
// -*- mode: C++ -*-
//
// Shows how to run AccelStepper in the simplest,
// fixed speed mode with no accelerations
// Requires the AFMotor library (https://github.com/adafruit/Adafruit-Motor-Shield-library)
// And AccelStepper with AFMotor support (https://github.com/adafruit/AccelStepper)
// Public domain!

// you can change these to DOUBLE or INTERLEAVE or MICROSTEP!

Stepper Motor Random Run Sequence with Wait Time

// to motor port #2 (M3 and M4)

}
void loop() {
  {
  Serial.println("Double coil steps");
