Draw a circuit schematic and write an ardunio code which has some specific properties as the following with using uln2003a (stepper motor driver), one unipolar stepper motor, one button, one potentiometer, and one lcd display

a. When the button is pressed, the stepper motor performs half cycle rotation in counter clock wise direction , wait 3 seconds, and moves back to its original position. The system will repeat this procedure 3 times while waiting one second between cycles.

b. The speed of the stepper motor should be controlled by potentiometer.

c. The number of cycles( one cycle means that when the button is pressed, the stepper motor performs half cycle rotation in counter clock wise direction , wait 3 seconds, and moves back to its original position.) should be written in lcd display.
