Design of Motion Profile of Stepper Motor for Elevator Using Arduino Uno

Elevators are one of the most important inventions in human history, are one of the key players in shaping urbanization of our society and required technological advancements to continue their safe and efficient use. Nowadays, many motion profiles are used in an elevator to improve its efficiency and comfortably of human beings. This paper will present the design and simulation of the motion profile of a stepper motor which comprises the use of the Arduino microcontroller and Arduino code to produce optimize motion profile output and it will use in the elevator system to get its high efficiency and accuracy. A timer interrupts program is written in Arduino IDE for stepper motor in point-to-point motion method for a given time to reach its constant acceleration/deceleration and maximum speed. A graph of this motion profile is plotted in excel from the time output of the serial plotter of Arduino IDE versus the speed that is given in the program of the motor
