Quentin, Welcome Aboard!

You will get up to good speed here!

Enjoy!

Hi Everyone.  My name is Gene.  You might not believe this but I have a PhD in EE and have never before worked with actually programming microprocessors even though I know all about the underlying amazing physics that made these devices possible.  Thank quantum physics. 🙂  Without that theory the transistor would never have been invented or discovered, much less minimized to what we have today.  But I have so much to learn now about the language and use of these very handy devices.

I am embarking on a small project that ought to be very simple as all it requires is controlling a stepper motor (actually 2 in unison) with a tiny microprocessor.  Ultimately I'd like to use my iPhone to finish the control aspects, but I want to start simple and learn the process of controlling it from the board.  

So I have a tiny Emakefun BLE Nano board (due to size limits of my final project) which is supposed to be totally compatible with Arduino.  And it houses Bluetooth as well, which is nice.  And I have two bipolar stepper motors (requiring less than 1 A each) and the Grove 12C driver board.  

My challenge right now is figuring out how to connect the Grove driver board to the BLE Nano!  I've watched several videos, even one from this group on the Toshiba chip that's part of the Grove driver, but that was not helpful in connecting my driver board to the BLE Nano.  At this point I have uploaded a simple stepper motor sketch to the BLE nano so I just want to do the physical connection and make sure it works before I modify the sketch.  Hopefully, between my continued research and help from this Forum, I'll get this up and running soon.

Hi Gene!

Welcome aboard!

Sound like you're on the way to REAL FUN with these lil gems with SO MUCH potential!

You might check-out Paul McWhorter on Page 28 of this thread...  Just key-in 28 in the desired Page No. you want to look at and you will see the links to possibly learn a little more about things from Ground Zero, UP...

Of course Bill's videos here are Super and should be a LOT of help to you... as well as this Forum to get direct questions answered...

Just Search for the subject you need help with...  if not found, Start a new Topic and lay it out to us for help.

Enjoy!

Hi Joe, 

Thanks for the warm welcome.  

I have been poking around here to try to find the proper way to INTRODUCE a new topic, since it doesn't appear now in your SEARCH box.  It turns out I was spending far too much time learning how to connect my stepper motor driver simply because its a GROVE 12c driver board and I've now learned how to relate their proprietary connector description to the standard IN1, IN2, IN3, IN4 labels used on Arduino.  

Maybe this information will be helpful to others, so if you'd like me to post it, please guide me to the way to do that here.

Who am I : Multi media designer 17years and counting.

Why Arduino : Well with the reality of what is happening, I am looking at retrenchment. I lost 2 family members in 1 month. Before this lockdown started I had a project that I wanted to start, a way to hire out a trimming machine, and make a few cents. I bought everything I thought I would need, then ran into problems. The biggest problem is writing or programming a sketch 🙂 

I watched a video by (Dronebot workshop - Big Stepper Motors with Arduino), and I am on facebook groups trying to turn my dream into a reality BUT I would also like to know more about sketches / programming as I would like to upgrade my project in time.

I will post my project files and photos a bit later. I hope everyone is safe.
God Bless

Very good, Gene...

Those minor details will get you every time!

Check out Paul McWhorter...  on page 28 of this thread...  He will teach from Ground Zero...

You will be programming in No-Time!

Just enter page 28 in place of the 43 in lower right corner of this post...

... follow nose...

Hi Squish!

Welcome aboard!  You have some real SAVVY grandkids!!   GOOD!!

I, personally, can't help you with your robo-car...  BUT, there are people here that can!

Thank you for keeping us updated on your problem & the solution...

Take care...  be safe.
