set the maximum speed, acceleration factor, // initial speed and the target position for motor 1 Creates two instances // Pins entered in sequence IN1-IN3-IN2-IN4 for proper step sequenceĪccelStepper stepper1(HALFSTEP, 8, 10, 9, 11) ĪccelStepper stepper2(FULLSTEP, 4, 6, 5, 7) To install the library, navigate to Sketch > Include Library > Manage Libraries… Wait for the Library Manager to download the libraries index and update the list of installed libraries. This library is not included with the Arduino IDE, so you’ll need to install it first. It supports multiple steppers at once, with independent concurrent stepping on each stepper.It supports acceleration and deceleration.It outperforms the standard Arduino Stepper library in the following ways: So, for our next experiment, we will use an advanced stepper motor library – the AccelStepper library. However, if you want to control multiple steppers, you’ll need a more powerful library. The Arduino Stepper Library is perfect for simple, single-motor applications. Arduino Example Code 2 – Using AccelStepper library For example, on a 100-step motor, if you set the speed to 1 RPM and call step(100), this function will take a full minute to finish. This means that the Arduino will wait until the motor stops running before proceeding to the next line in your sketch. Please keep in mind that step() is a blocking function.
