This means that we can control the stepper motor with. A while back I went over Stepper Motor Basics using just such buttons to control bipolar stepper motors. For that an external driver is required. These L298N driver boards will drive one stepper motor per board.
Four Arduino digital outputs are required to drive a single motor. This driver was picked up on ebay for under $3.
L298N motor driver IC, a 5V regulator, and protection diodes. This tutorial will show you how to operate a stepper motor that was salvaged from an old printer with an Arduino. For running a stepper motor from an Arduino these are the main ways to go. Typically sold with small geared steppers this . This library allows you to control unipolar or bipolar stepper motors. To use it you will need a stepper motor , and the appropriate hardware to control it.
This is suggested wiring for running the examples unmodified. All the pins below can be changed. All of these examples are going to be done with my Easy Driver and Big Easy Driver stepper motor driver boards driving several different random stepper motors I have lying around the lab.
I will be generating the step and direction pulses with an Arduino UNO and a chipKIT UNO3 although all of these examples should .
