Control Two Stepper Motors with Wii Nunchuk via Adafruit Motor Shield???

Using Arduino Project Guidance
1

Hi all! I hope someone here can point me in the right direction. I have a project in mind, and I am hoping to control two motors with a Nunchuk connected to an Arduino. To that end, I have an Arduino Uno, an Adafruit Motor Shield V2, and an original Nitendo Wii Nunchuk. Thinking their movement would be more precise and easier to control, I purchase two stepper motors for this project. I have tried piecing together snippets of code from various tutorials I've found, but I am just a beginner with Arduino programming, and I cannot figure out what to do to make the Nunchuk actually control even just one motor. I can get both stepper motors doing "something" using the example code included with the Adafruit Motor Shield, so I'm fairly sure the motor shield is soldered and working correctly. I have at times found code that seems to read the movements of the Nunchuk joystick and prints the output on the serial monitor, but that output seems to be inconsistent. This could be due to the fact that I've read that the Nunchuk can be noisy, or it could be because I don't know what I'm doing.

So I was hoping to ask first and foremost: Is it even possible (or advisable) to control two stepper motors with the Nunchuk by using the Adafruit motor shield? Would using regular motors be easier as far as the coding?

I found several tutorials online, and a few posts on this forum talknig about similar projects, but I haven't found on that specifically combines the Nunchuk, stepper motors, and the Adafruit Motor Shield V2. I'm not asking for someone to write my code, but if you could point me in the right direction I would be very appreciative.

I tried to keep my post short, but clearly I'm a noob :wink: If you need any additional info about my project, please just ask, I'll be watching for replies.

Thank you very much for your help!

I don't know anything about Wiis. If you can get data from a Wii then you will be able to control a stepper motor with it.

Post a link to the datasheet for the stepper motors.

A motor shield is a poor choice for driving stepper motors. A specialised stepper driver would be better, but without the datasheet for the motor I can't suggest anything.

Is your Nunchuk connected correctly? Directly or via a breakout board? The Nunchuk uses I2C, but you can use a library that handles that for you and give you the values of the joystick, the buttons and the accelerometer, so that should be quite easy.
If you can control your motors the next step would be to use the Nunchuk values to control your motors accordingly. The Adafruit motor library is well documented and should be ready to use.
If you have problems please post your code and describe where the problem is.
