    • MotorHelper

      public MotorHelper(com.pi4j.io.pwm.Pwm motor, com.pi4j.io.gpio.digital.DigitalOutput pin1, com.pi4j.io.gpio.digital.DigitalOutput pin2)
      Constructs a new MotorHelper.
      Parameters:
      motor - A PWM interface to control the motor.
      pin1 - A DigitalOutput interface for the first GPIO pin.
      pin2 - A DigitalOutput interface for the second GPIO pin.

  • Method Details

    • enable

      public void enable()
      Enables the DC motor by setting an initial duty cycle and frequency. The motor remains disabled until this method is called.

    • disable

      public void disable()
      Disables the motor, effectively stopping any ongoing PWM signal.

    • setSpeed

      public void setSpeed(double speed)
      Sets the speed of the DC motor. This method calculates the necessary pulse width and duty cycle to achieve the specified speed.
      Parameters:
      speed - the target speed for the motor, as a percentage between 0 and 100.

    • setClockwise

      public void setClockwise(boolean clockwise)
      Sets the direction of the DC motor.
      Parameters:
      clockwise - whether the motor should rotate clockwise.

    • switchDirection

      public void switchDirection()
      Switches the direction of the motor.
