/*
|
||||
Stepper Motor Control - one step at a time
|
||||
|
||||
This program drives a unipolar or bipolar stepper motor.
|
||||
The motor is attached to digital pins 8 - 11 of the Arduino.
|
||||
|
||||
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.
|
||||
|
||||
Use this also to count the number of steps per revolution of your motor,
|
||||
if you don't know it. Then plug that number into the oneRevolution
|
||||
example to see if you got it right.
|
||||
