Stepper Motor Intro and Trapeziodal Velocity Profile

In today's video I give a basic introduction to stepper motors, what's inside and what makes them tick. If you've ever used a stepper motor and want to control it in a more advanced fashion than simply pulsing on and off, we take a look at a trapezoidal velocity profile to smoothly accelerate and decelerate from start to endpoint. Some discussion is also provided about why one would want to do such a thing. A stepper motor is connected to a linear actuator and we go over the basic calculations on how to determine the number of steps to travel a specific distance.
