Notes<\/h2>\n
The 28BYJ-48 Stepper has 2048 steps per revolution. \u00a0With the example code above the stepper \u00a0cannot do more than about 14 RPM. \u00a0With the above code, the stepper will rotate 360 degrees in one direction pause for 1\/2 second and then rotate 360 degrees in the opposite direction.<\/p>\n
