Arduino: operate stepper motor - how it works
A stepper motor does not turn when a voltage is applied, but takes small steps. With the Arduino you can easily control such a motor. You can find out how to do this in this practical tip.
Arduino: operate stepper motor - how it works
A stepper motor is an electromechanical device that converts electrical impulses into discrete mechanical movements. To control such a stepper motor with the Arduino, you need a stepper motor driver board. Connect all components as shown in the picture.
- You must then import the required library using the "#include" command.
- With the command "const int stepsPerRevolution = 1500;" determine how many steps the motor should take in one revolution.
- Depending on how you connected the stepper, you have to create a new stepper object. You can do this with the command "Stepper myStepper (stepsPerRevolution, 8, 10, 9, 11);".
- Now set the speed in the setup method: "myStepper.setSpeed (20);".
- Now you can use the command "myStepper.step (stepsPerRevolution);" say this should make a full turn clockwise.
