1- The push button should be used to monitor the direction of the motor. Once the push button is pressed the direction of the motor should be changed. 2- If the motor is running in the clockwise direction (+) the green LED should be ON and the red LED should be OFF. But if the motor is running in the counterclockwise direction (-) the red LED should be ON and the green LED should be OFF. 3- The potentiometer should be used to control the speed of the stepper motor. 4- A tune will be generated by the buzzer when the motor is set at the maximum speed by the potentiometer. (Hint: Use the motor driver L293D as shown in the figure below)

2. Question:
Design an Arduino project to use a potentiometer, one push button, one buzzer and two
LEDS (red and green) to control a stepper motor as following:
1- The push button should be used to monitor the direction of the motor. Once the push
button is pressed the direction of the motor should be changed.
2- If the motor is running in the clockwise direction (+) the green LED should be ON
and the red LED should be OFF. But if the motor is running in the counterclockwise
direction (-) the red LED should be ON and the green LED should be OFF.
3- The potentiometer should be used to control the speed of the stepper motor.
4- A tune will be generated by the buzzer when the motor is set at the maximum speed
by the potentiometer.
