For this particular project, we chose to use a motor shield to make the code simpler. In this case, we bought an Adafruit Motor Shield V2 for Arduino. Adafruit has created their own library to go with the motor shield. The library contains shortcuts for running servos, DC motors, and steppers. In addition, it is compatible with the AccelStepper library. The AccelStepper library is what we mainly use. It gives the user control of the stepper using position, velocity, and acceleration functions. Using the position function, we are able to write a mathematical equation to express the position we want the stepper at with respect to time. Using some calculus, we can extend this and make use of the velocity and acceleration functions if we wanted to.

Latest manual of new the motors code is presenting even more interesting and contain many stunning facts. It is very shocking for me that it is also present on many other machine codes. I am getting help from youressayreviews source to write some papers to spread awareness of education among the youth.
