Being new to arduino could you please explain for me. Thanks for the great work! It saved me a lot of time! Hello Dejan, Trying to control a stepper motor with a manual pulse generator hand wheel type. Inside a huge PCB factory: The 4 logic pins will then connect to the Arduino 8, 9, 10, and 11 in this tutorial. I would like to run two steppers with one arduino and 2 A but with one power supply.

Well you should adjust the delay time between the steps that will suit your driver and stepper capabilities and match your desired speed. Arduinoo the Step pin we control the mirosteps of the motor and with each pulse sent to this pin the motor moves one step. What code needs to be added? Best regards Markus Reply.

Just found your website and the answers to what has has been puzzling me regarding stepper motors. Sure you can, but you have to make a program for that. De 28byj48 met ULN driver boards beschikken over vier uitgangen, die allen aangesloten worden op de Arduino.

How To Control a Stepper Motor with A4988 Driver and Arduino

In order to check this I uploaded a simple code that sends continuous logic high to the Step pin so that we can better notice the current and connected my meter in series with one winding of the motor and powered it up. The 1A and 1B pins will be connected to one coil of the motor and the 2A and 2B pins to the other coil of the motor.


If it is possible, can you give me some pointers or things to remember? Your battery might not have enough power to drive the motor.

Before we connect the motor we should adjust the current limiting of the driver so that we are sure that the current is within the current limits of the motor. I tried the same circuit with NEMA But now its working… Great!. In your tutorial you have only one direction and your values are from 0 to Here we also need to mention that these 2 pins are not pulled to any voltage internally, so we should not leave them floating in our program.

But result is like on the video. Check your power supply amps rating, make sure it has enough power for driving the motor.

By using our website, you agree to our use of cookies. You could try to lower the current draw of the motor by adjusting the potentiometer on the A driver, and in that way lower the motor heat.

Try increasing the delay time between the steps. Thanks in advance, still your tutorial was very helpfull. I am developing an automated arbiter of the game of the generals if you are familiar with this game and an stepper motor is needed to position the robotic arm in 8 rows of the board.


Arduino – Stepper

Does this not lead to any conflicts? With slight pressure tangential to the shaft it is making a microstep movement. The 4 logic pins will then connect to the Arduino 8, 9, 10, and 11 in this tutorial. Do you mind answering as to what the difference is between this driver and the one used for the 28bjystepper? Between each digitalWrite we need add some delay from which the speed of the motor will depend.

In the loop section first we will set the Direction pin on high state that will enable the motor to move in a particular direction.

The lowest ardiuno time fastest speed I managed to try was like 90, but with higher delay at the start, more thenthen lowering with the potentiometer to I had tried all the combinations. Hello and nice work!

Thank you in advance.

Arduino – Stappenmotor (28BYJ)

I would like to run two steppers with one arduino and 2 A but with one power supply. Now, the A has a minimum operating voltage of 8 V.

Try reconnect the driver exactly as explained and try the code again.
