This article includes everything you need to know about controlling a 28BYJ stepper motor with the ULN driver board and Arduino. I have included datasheets, a wiring diagram, and many example codes!

First we take a look at the easy to use Arduino Stepper library. This library is great when you are just starting out, but doesn’t have many extra features.

I highly recommend to also take a look at the example codes for the AccelStepper library at the end of this tutorial. This library is fairly easy to use and can greatly improve the performance of your hardware.

After each example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs.

If you want to learn more about controlling larger stepper motors with more torque and more speed, take a look at the articles below. In these articles I teach you how to control NEMA 17 stepper motors, with drivers like the A

Information about the 28BYJ stepper motor and ULN driver board

The 28BYJ is one of the cheapest stepper motors you can find. Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors.

This motor is often used to automatically adjust the vanes of an air conditioner unit. It has a built-in gearbox, which gives it some extra torque and reduces the speed drastically.

Below you can find the specifications for both the stepper motor and driver that are used in this tutorial.

For more information you can check out the datasheet here.

Important note: Manufacturers usually specify that the motors have a gear reduction. Some members of the Arduino Forums noticed that this wasn’t correct and so they took some motors apart to check the actual gear ratio. They determined that the exact gear ratio is in fact , which results in approximately  steps per full revolution (in half step mode).

I am not sure if all manufacturers use the exact same gearbox, but you can just adjust the steps per revolution in the code, to match your model.

The Adafruit Industries Small Reduction Stepper Motor uses the same form factor as the 28BYJ, but does have a different gear ratio. It has a roughly 1/16 reduction gear set, which results in steps per revolution (in full-step mode). You can download the datasheet for it here.

For more information about the driver you can check out the datasheet below.


Wiring – Connecting 28BYJ stepper motor and ULN driver board to Arduino UNO

The wiring diagram/schematic below shows you how to connect the ULN driver board to the 28BYJ stepper motor and the Arduino. The connections are also given in the table below.

28BYJStepper-Motor-ULNDriver-Wiring-Diagram-Schematic-Pinout

I used a breadboard and some jumper wires to connect the driver board to an external power supply.

ULN and 28BYJ to Arduino Connections

ULN Driver BoardConnection
IN1Pin 8 Arduino
IN2Pin 9 Arduino
IN3Pin 10 Arduino
IN4Pin 11 Arduino
Logic GND Arduino
GND power supply
+5 V power supply

Please note: It is possible to directly power the stepper motor from the 5 V output of the Arduino. This however, is not recommended. When the stepper motor draws too much current you can damage the Arduino. I also found that when powering the Arduino with USB power only, I would get inconsistent behavior and bad performance of the stepper motor.

I recommend to power the driver board/stepper motor with an external 5 V power supply, like this one. It should come with a female DC connector, so you can easily connect it to some (jumper) wires. Note that you also need to connect the GND of the Arduino to the – pin on the ULN driver board.

After uploading the code you also need to power the Arduino, either with a USB type-B cable or via the mm power jack.

The jumper next to power connections on the driver board can be used to disconnect power to the stepper motor.


Basic Arduino example code to control a 28BYJ stepper motor

You can upload the following example code to your Arduino using the Arduino IDE.

This example uses the Stepper.h library, which should come pre-installed with the Arduino IDE. This sketch turns the stepper motor 1 revolution in one direction, pauses, and then turns 1 revolution in the other direction.

/* Example sketch to control a 28BYJ stepper motor with ULN driver board and Arduino UNO. More info: https://www.makerguides.com */ // Include the Arduino Stepper.h library: #include <Stepper.h> // Define number of steps per rotation: const int stepsPerRevolution = ; // Wiring: // Pin 8 to IN1 on the ULN driver // Pin 9 to IN2 on the ULN driver // Pin 10 to IN3 on the ULN driver // Pin 11 to IN4 on the ULN driver // Create stepper object called 'myStepper', note the pin order: Stepper myStepper = Stepper(stepsPerRevolution, 8, 10, 9, 11); void setup() { // Set the speed to 5 rpm: myStepper.setSpeed(5); // Begin Serial communication at a baud rate of Serial.begin(); } void loop() { // Step one revolution in one direction: Serial.println("clockwise"); myStepper.step(stepsPerRevolution); delay(); // Step one revolution in the other direction: Serial.println("counterclockwise"); myStepper.step(-stepsPerRevolution); delay(); }

Code explanation:

The sketch starts by including the Stepper.h Arduino library. More information about this library can be found on the Arduino website.

// Include the Arduino Stepper.h library: #include <Stepper.h>

Next, I defined how many steps the motor takes to rotate 1 revolution. In this example we will be using the motor in full-step mode. This means it takes steps to rotate degrees (see motor specifications above).

// Define number of steps per rotation: const int stepsPerRevolution = ;

Next, you need to create a new instance of the Stepper class, which represents a particular stepper motor connected to the Arduino. For this we use the function  where steps is the number of steps per revolution and pin1 through pin4 are the pins to which the motor is connected. To get the correct step sequence, we need to set the pins in the following order: 8, 10, 9,

PCBWay
// Create stepper object called 'myStepper', note the pin order: Stepper myStepper = Stepper(stepsPerRevolution, 8, 10, 9, 11);

In this case I called the stepper motor ‘myStepper’ but you can use other names as well, like ‘z_motor’ or ‘liftmotor’ etc. . You can create multiple stepper motor objects with different names and pins. This allows you to easily control 2 or more stepper motors at the same time.

In the setup, you can set the speed in rpm with the function . The maximum speed for a 28byj stepper motor is roughly rpm at 5 V.

void setup() { // Set the speed to 5 rpm: myStepper.setSpeed(5); // Begin Serial communication at a baud rate of Serial.begin(); }

In the loop section of code, we simply call the  function which turns the motor a specific number of steps at a speed determined by the  function. Passing a negative number to this function reverses the spinning direction of the motor.

void loop() { // Step one revolution in one direction: Serial.println("clockwise"); myStepper.step(stepsPerRevolution); delay(); // Step one revolution in the other direction: Serial.println("counterclockwise"); myStepper.step(-stepsPerRevolution); delay(); }

Example codes for 28BYJ stepper motor with Arduino and AccelStepper library

In the following three examples I will show you how you can control both the speed, the direction and the number of steps the stepper motor should take. In these examples I will be using the AccelStepper library.

The AccelStepper library written by Mike McCauley is an awesome library to use for your project. One of the advantages is that it supports acceleration and deceleration, but it has a lot of other nice functions too.

You can download the latest version of this library here or click the button below.

You can install the library by going to Sketch > Include Library > Add .ZIP Library… in the Arduino IDE.

Another option is to navigate to Tools > Manage Libraries… or type Ctrl + Shift + I on Windows. The Library Manager will open and update the list of installed libraries.

You can search for ‘accelstepper‘ and look for the library by Mike McCauley. Select the latest version and then click Install.

Installing an Arduino library step 2 AccelStepper

1. Continuous rotation example code

The following sketch can be used to run one or more stepper motors continuously at a constant speed. (No acceleration or deceleration is used).

You can copy the code by clicking on the button in the top right corner of the code field.

/* Example sketch to control a 28BYJ stepper motor with ULN driver board, AccelStepper and Arduino UNO: continuous rotation. More info: https://www.makerguides.com */ // Include the AccelStepper library: #include <AccelStepper.h> // Motor pin definitions: #define motorPin1 8 // IN1 on the ULN driver #define motorPin2 9 // IN2 on the ULN driver #define motorPin3 10 // IN3 on the ULN driver #define motorPin4 11 // IN4 on the ULN driver // Define the AccelStepper interface type; 4 wire motor in half step mode: #define MotorInterfaceType 8 // Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper library with 28BYJ stepper motor: AccelStepper stepper = AccelStepper(MotorInterfaceType, motorPin1, motorPin3, motorPin2, motorPin4); void setup() { // Set the maximum steps per second: stepper.setMaxSpeed(); } void loop() { // Set the speed of the motor in steps per second: stepper.setSpeed(); // Step the motor with constant speed as set by setSpeed(): stepper.runSpeed(); }

How the code works:

Again the first step is to include the library with .

// Include the AccelStepper library: #include <AccelStepper.h>

The next step is to define the ULN to Arduino connections.

The statement  is used to give a name to a constant value. The compiler will replace any references to this constant with the defined value when the program is compiled. So everywhere you mention , the compiler will replace it with the value 8 when the program is compiled.

// Motor pin definitions: #define motorPin1 8 // IN1 on the ULN driver #define motorPin2 9 // IN2 on the ULN driver #define motorPin3 10 // IN3 on the ULN driver #define motorPin4 11 // IN4 on the ULN driver

The next step is to specify the motor interface type for the AccelStepper library. In this case we will be driving a 4 wire stepper motor in half step mode, so we set the interface type to ‘8’. You can find the other interface types here. If you want to run the motor in full-step mode (fewer steps per revolution), just change the 8 to 4.

// Define the AccelStepper interface type; 4 wire motor in half step mode: #define MotorInterfaceType 8

Next, you need to create a new instance of the AccelStepper class with the appropriate motor interface type and connections. To get the correct step sequence, we need to set the pins in the following order: motorPin1, motorPin3, motorPin2, motorPin4.

In this case I called the stepper motor ‘stepper’ but you can use other names as well, like ‘z_motor’ or ‘liftmotor’ etc. . You can create multiple stepper motor objects with different names and pins. This allows you to easily control 2 or more stepper motors at the same time.

// Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper library with 28BYJ stepper motor: AccelStepper stepper = AccelStepper(MotorInterfaceType, motorPin1, motorPin3, motorPin2, motorPin4);

In the setup section of the code, we define the maximum speed in steps/second with the function . Speeds of more than steps per second can be unreliable, so I set this as the maximum. Note that I specify the name of the stepper motor (‘stepper’), for which I want to define the maximum speed. If you have multiple stepper motors connected, you can specify a different speed for each motor: .

void setup() { // Set the maximum steps per second: stepper.setMaxSpeed(); }

In the loop, we first set the speed that we want the motor to run at with the function . (you can also place this in the setup section of the code).

 polls the motor and when a step is due it executes 1 step. This depends on the set speed and the time since the last step. If you want to change the direction of the motor, you can set a negative speed:  turns the motor the other way.

void loop() { // Set the speed of the motor in steps per second: stepper.setSpeed(); // Step the motor with constant speed as set by setSpeed(): stepper.runSpeed(); }

In half step mode, one revolution takes steps, so steps/sec results in roughly 7 rpm.


2. Sketch to control number of steps or revolutions

With the following sketch you can control both the speed, direction and the number of steps/revolutions.

In this case, the stepper motor turns 1 revolution clockwise with steps/sec, then turns 1 revolution counterclockwise at steps/sec, and lastly turns 2 revolutions clockwise at steps/sec.

/* Example sketch to control a 28BYJ stepper motor with ULN driver board, AccelStepper and Arduino UNO: number of steps/revolutions. More info: https://www.makerguides.com */ // Include the AccelStepper library: #include <AccelStepper.h> // Motor pin definitions: #define motorPin1 8 // IN1 on the ULN driver #define motorPin2 9 // IN2 on the ULN driver #define motorPin3 10 // IN3 on the ULN driver #define motorPin4 11 // IN4 on the ULN driver // Define the AccelStepper interface type; 4 wire motor in half step mode: #define MotorInterfaceType 8 // Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper library with 28BYJ stepper motor: AccelStepper stepper = AccelStepper(MotorInterfaceType, motorPin1, motorPin3, motorPin2, motorPin4); void setup() { // Set the maximum steps per second: stepper.setMaxSpeed(); } void loop() { // Set the current position to 0: stepper.setCurrentPosition(0); // Run the motor forward at steps/second until the motor reaches steps (1 revolution): while (stepper.currentPosition() != ) { stepper.setSpeed(); stepper.runSpeed(); } delay(); // Reset the position to 0: stepper.setCurrentPosition(0); // Run the motor backwards at steps/second until the motor reaches steps (1 revolution): while (stepper.currentPosition() != ) { stepper.setSpeed(); stepper.runSpeed(); } delay(); // Reset the position to 0: stepper.setCurrentPosition(0); // Run the motor forward at steps/second until the motor reaches steps (2 revolutions): while (stepper.currentPosition() != ) { stepper.setSpeed(); stepper.runSpeed(); } delay(); }

Code explanation:

The first part of the code up to the loop() section is exactly the same as in the previous example.

In the loop I make use of a while loop in combination with the  function. First, I set the current position of the stepper motor to zero with .

// Set the current position to 0: stepper.setCurrentPosition(0);

Next, we make use of the while loop. A while loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. So in this case I check if the current position of the stepper motor is not equal to steps (!= means: is not equal to). While this is not the case, we run the stepper motor at a constant speed as set by .

// Run the motor forward at steps/second until the motor reaches steps (1 revolution): while (stepper.currentPosition() != ) { stepper.setSpeed(); stepper.runSpeed(); }

In the rest of the loop, we do exactly the same, just with a different speed and target position.


3. Acceleration and deceleration example code

With the following sketch you can add acceleration and deceleration to the movements of the stepper motor, without any complicated coding. The first section of this sketch is the same as in example 1, but the setup and the loop are different.

The motor will run two revolutions back and forth with a speed of steps per second and an acceleration of steps/second2.

/* Example sketch to control a 28BYJ stepper motor with ULN driver board, AccelStepper and Arduino UNO: acceleration and deceleration. More info: https://www.makerguides.com */ // Include the AccelStepper library: #include <AccelStepper.h> // Motor pin definitions: #define motorPin1 8 // IN1 on the ULN driver #define motorPin2 9 // IN2 on the ULN driver #define motorPin3 10 // IN3 on the ULN driver #define motorPin4 11 // IN4 on the ULN driver // Define the AccelStepper interface type; 4 wire motor in half step mode: #define MotorInterfaceType 8 // Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper library with 28BYJ stepper motor: AccelStepper stepper = AccelStepper(MotorInterfaceType, motorPin1, motorPin3, motorPin2, motorPin4); void setup() { // Set the maximum steps per second: stepper.setMaxSpeed(); // Set the maximum acceleration in steps per second^2: stepper.setAcceleration(); } void loop() { // Set target position: stepper.moveTo(); // Run to position with set speed and acceleration: stepper.runToPosition(); delay(); // Move back to original position: stepper.moveTo(0); // Run to position with set speed and acceleration: stepper.runToPosition(); delay(); }

How the code works:

In the setup, besides the maximum speed, we also need to define the acceleration/deceleration. For this, we use the function .

void setup() { // Set the maximum steps per second: stepper.setMaxSpeed(); // Set the maximum acceleration in steps per second^2: stepper.setAcceleration(); }

In the loop section of the code, I used a different way to let the motor rotate a predefined number of steps. First I set the target position with the function . Next, we simply use the function  to let the motor run to the target position with the set speed and acceleration. The motor will decelerate before reaching the target position.

void loop() { // Set target position: stepper.moveTo(); // Run to position with set speed and acceleration: stepper.runToPosition(); delay(); // Move back to original position: stepper.moveTo(0); // Run to position with set speed and acceleration: stepper.runToPosition(); delay(); }

Finally, we set the new target position back to the 0, so that we return to the origin.

28BYJ - 5V Stepper Motor

The BYJ48 Stepper Motors are one of the most commonly used stepper motors. You can find this or similar motors in your DVD drives, Motion camera and many more similar devices. The motor has a 4 coil unipolar arrangement and each coil is rated for +5V hence it is relatively easy to control with any basic microcontrollers.

Where to use BYJ48 Stepper Motor

These kind of motors are commonly used in your DVD drives, Motion camera and other similar applications. The motor has a 4 coil unipolar arrangement and each coil is rated for +5V hence it is relatively easy to control with any basic microcontrollers. These motors has a stride angle of °/64, this means that the motor will have to make 64 steps to complete one rotation and for every step it will cover a ° hence the level of control is also high. However, these motors run only on 5V and hence cannot provide high torque, for high torque application you should consider the Nema17 motors. So if you are looking for a compact easy to use stepper motor with decent torque then this motor is the right choice for you.

 

How to use BYJ48 Stepper Motor

These stepper motors consume high current and hence a driver IC like the ULN is mandatory. To know how to make this motor rotate we should look into the coil diagram below.

Stepper motor coil diagram

As we can see there are four coils in the motor and one end of all the coil is tied to +5V (Red) and the other ends (Orange, Pink, Yellow and Blue) are taken out as wires. The Red wire is always provided with a constant +5V supply and this +5V will be across (energize) the coil only if the other end of the coil is grounded. A stepper motor can be made to rotate only if the coils are energized (grounded) in a logical sequence. This logical sequence can be programmed using a microcontroller or by designing a digital circuit. The sequence in which each coil should be triggered is shown in the table below. Here “1” represent the coil is held at +5V, since both the ends of coil is at +5V (red and other end) the coil will not be energised. Similarly “0” represents the coil is held to ground, now one end will be +5V and the other one is grounded so the coil will be energised.

Converting 28byj 48 stepper motor to bipolar

28BYJ is a uni-polar 5V stepper motor that takes electrical signals as input and rotates by converting these input signals into the mechanical rotation. It consists of 4 stationary coils rated at +5V. These coils are known as a stator and make a ring around the rotor. It has a 1/64 reduction gear set and therefore moves in precise steps per revolution. These motors are silent in comparison to other DC motors and servo motors. You can achieve positional control easily without needing extra circuitry and components.

28BYJ 5V Stepper Motor Pin Configuration

You can see from the diagram given below 5 wires are projecting out from the motor. Among them, red wire is for voltage supply. It is connected to the +5V supply. The remaining four wires are of four static coils. This picture shows a pinout diagram of 28BYJ 5V Stepper Motor.

The ULN breakout board has high current and voltage than a single transistor and therefore it can drive a stepper motor easily by enabling a microcontroller. The connections are simple. Connect the output pins of the driver IC with the four coils of the stepper motor and supply a positive voltage at the red wire of a stepper motor.

Interfacing with Arduino

28BYJ 5V Stepper Motor interfacing with Arduino

Connect the digital pins of Arduino with the input pins of the ULNA driver IC. You can use the full step method for rotation, but half step method is recommended for rotation of this stepper motor. In the half-step method, coil 1 is powered first. After then supply power to both coil 1 and coil 2 together. Then supply power to coil 2. Follow the same sequence in the next steps.

Switching Sequence Table

When you send certain control signals, the stepper motor starts rotating. 28BYJ Stepper motor has a wide use in industrial applications and robotics. It is a 4 phase stepper motor. It is very widely used. 28BYJ is usually sold with the driver circuit next to it. It is necessary to use drive modules to start stepper motors. Because the motors draw a lot of current. This is more than the current that microcontrollers like arduino can provide. We will show 28BYJ pinout also.

It provides the necessary signals for the stepper motor with its integrated circuit. The rotational speed of the stepper motor can be changed with the arrival speed of the signals. By replacing a 10 kilo ohm potentiometer, you can change the period of the square wave signal given by the integration. Thus, the driver can change the speed of the stepper motor. Here the video:
