This project will make BYJ48 Stepper Motor to make clockwise and counter clockwise rotating. Flowing pictures show the stepper motor and connection bridge circuit board:
stepper3stepper

Step 1 – Connect Arduino, Bridge board and Stepper Motor as per following graph:
stepper2

Step 2 Download stepper.ino sketch file and load it into Arduino. The step motor will start to rotate clockwise and counter clockwise.

    How do you control the speed of the motor with a potentiometer?

    I am using the following code, but it is not working. The motor seems as if it is trying to do something, but I think it is just stepping back and forth.

    /*
    Stepper Motor Control – speed control

    This program drives a unipolar or bipolar stepper motor.
    The motor is attached to digital pins 8 – 11 of the Arduino.
    A potentiometer is connected to analog input 0.

    The motor will rotate in a clockwise direction. The higher the potentiometer value,
    the faster the motor speed. Because setSpeed() sets the delay between steps,
    you may notice the motor is less responsive to changes in the sensor value at
    low speeds.
