I’m building an electric trainset for my Grandson and am having difficulty getting the turntable to work properly when controlled by an Arduino. I was wondering if the EasyDriver Stepper motor driver would work instead of the Arduino.

Hey @Lysardman,
Welcome to the RobotShop community!
From two quick searches online, I can confirm the following details:
- The 28BYJ-48 seems to use very little power, probably in the range of 40 mA per channel.
- The EasyDriver Stepper Motor can provide up-to 750 mA per channel.
Therefore, even if the specs of the motor I found online or the stepper motor are quite off, you should be fine since they are well over an order of magnitude apart (in the proper way, of course!).
Feel free to reply here if you have further questions.
Sincerely,
P.-S.: Since you are making a new project, I highly recommend you post about it here. It doesn’t have to be complete or with many details at first but it would certainly help you get more assistance more easily if needed later.

Many thanks for your prompt reply.
I’m having a great deal of problem sorting out the coding I need for the turntable. I’ve been trying coding on and of for the past 40 years and have never really had any success. I’m just a simple, old, biochemist. LOL

No problem! I was taking a break when I noticed your post… good timing overall! 
Ah, yes, it can be difficult, especially if parts of the basics escape your gaze! I then recommend even more to follow that link in my last response and post some details about your project, such as:
- Mechanics, such as the table itself (size, weight, expected load, etc.).
- Actuators, such as your stepper motor mentioned in your original post and anything else related.
- Electronics, which includes your stepper motor controller, microcontroller/SBC (single board computer), etc.
- Software, what libraries you intend to use, platform/IDE/tool chain/etc., what examples you’ve relied on and, of course, any code you’ve already made/tried/etc. and the results of those attempts.
Of course, this seems like a lot, but it would definitely help in guiding you to make sure your project succeeds and help you learn all that you need as you complete it.
You may also find some of the material available here (and elsewhere) helpful, such as:
- Arduino lessons (make sure to check all 9 of them!)
- How to make a robot series (10 lessons!)
- How to interpret DC motor specs
- Basics: How Do I Choose an Actuator?
- Basics: What is a Motor Controller?
- Basics: How Do I Choose a Battery?
There’s nothing more fun (to me, anyway) then learning things outside my main skill set!
