3 | Stepper Motor Control - one step at a time
|
---|
4 |
|
---|
5 | This program drives a unipolar or bipolar stepper motor.
|
---|
6 | The motor is attached to digital pins 8 - 11 of the Arduino.
|
---|
7 |
|
---|
8 | The motor will step one step at a time, very slowly. You can use this to
|
---|
9 | test that you've got the four wires of your stepper wired to the correct
|
---|
10 | pins. If wired correctly, all steps should be in the same direction.
|
---|
11 |
|
---|
12 | Use this also to count the number of steps per revolution of your motor,
|
---|
13 | if you don't know it. Then plug that number into the oneRevolution
|
---|
14 | example to see if you got it right.
