In the lesson I talk about my StepMotor library, designed to control unipolar and bipolar stepper motors.
With this publication, I begin a series of lessons about stepper motor control in the Arduino system. The first lesson is devoted to connecting unipolar stepper motors to Arduino.
In many of my developments, I use stepper motors. There are branches of precision mechanics in which they are irreplaceable. I will try to explain as simply as possible how the stepper motor operates, what it is.
