Lesson 19: One step at a time 
Overview 
In this lesson, the motor will step one step at a time, very slowly. You can use this to test 
that you've got the four wires of your stepper wired to the correct pins. If wired correctly, all 
steps should be in the same direction. You may also use this sketch to count the number 
of steps that your motor does in one revolution.
