Thread: Arduino uno R3 stepper motor control

This is unbelievable, 101 views and not one comment.

Surely one of our members has some experience with programming Arduino boards.

I'm getting more support from the metalwork forum, and this is an electronics topic.

Sorry Ken, I can't help...

I might be able to resurrect my MCS51 memories if I tried hard (it's been 15 years since I used that particular family of chips, so my machine code brain cells have probably rusted away), or maybe I could help with some code for PIC Micro's - mainly the 16F series which I used a couple of years ago. Not the Arduino stuff though, sorry.
For what you're trying to do (re - the camera slider), I'd probably use a simple pulse generator with a dedicated stepper drive. Even a 555 chip would do it simply enough, but you might have some variations in the time base for reliable duplication.
For me, I'd go with a 16Fxx micro and generate a pulse stream from that.

Maybe ask here - http://forum.arduino.cc/. I'm sure someone there will know how to do it...

I think you've got no responses because you've asked a hell of a lot. It's like saying I've got zero experience with metalworking, but I've bought a lathe and I want to make this part, can you give me step-by-step instructions how to do it. By the way, how do you get the lathe to hold the work?

The normal approach to getting up to speed on an Arduino is to read a few of the many tutorials on how to get started - this will cover how to connect it to your PC, how to write, compile and upload sketches and make it do basic things like flash an LED.

Then you'd hunt down some sample code for the stepper shield you have, try it out and see what it does. Then you'd start to modify it bit-by-bit until it does what you want it to.

Hi RustyArc,

I've ploughed through many programs, but without knowing what each step does and what each character means, I might as well be trying to read Greek.

I was just hoping one of our members had a program for controlling a stepper motor, forward, stop reverse and speed using Arduino.

Don't reckon I'm asking too much.

YouTube has some detailed tutorials
for example the ones linked above. These run from Arduino basics through to programming steppers

I have looked at some ardunio code and it looks very c like to me. I dont do much c anymore outside of windows drivers, but the go to book is kernaghan and ritchies book "the c programming language".

Understand that with c and everything microcontrollers, you need some basic understanding of the processor architecture, so you will need to back up the programming book with the data sheet for the particular processor.
