Introduction: Driving the Pm55L-048-hp69 With Arduino

In this instructable I will teach you how to wire your stepper to run it with the arduino board.

You will need:

  • Arduino board (mine is uno)
  • Breadboard and wires
  • ULN2803 or ULN2003
  • PM55L-048-HP69 stepper
  • Power suply for stepper (I'm using a 19V 1A since this stepper works on 24V)

Step 1: Wiring

Using this tutorial, I was able to find the wiring of my stepper.

So, if you are using the example from the stepper library stepper_one Revolution

you have to wire this way:

A to digital pin 11

C to digital pin 10

B to digital pin 9

D to digital pin 8

I'm actually using the ULN2803, but the only diference is the 2803 have more pins to work with.

Step 2: The Code

Since we are workingh a 48 steps stepper, you have to change the line const int stepsPerRevolution =200;

for const int stepsPerRevolution =48; if you don't make this chage, it won't work.


#include <Stepper.h>

const int stepsPerRevolution = 48;

Stepper myStepper(stepsPerRevolution, 8,9,10,11);

void setup() {

// set the speed at 60 rpm: myStepper.setSpeed(60);

// initialize the serial port: Serial.begin(9600);


void loop() {

// step one revolution in one direction:




// step one revolution in the other direction:






Now have fun with the code. It worked well within 10 to 180 rpm.

Good luck, hope you like it.
