I am actually not sure of the stall amps. I would need to measure it I presume. There was no spec on that, but the only spec I did see on this page http://www.sparkfun.com/datasheets/Robotics/SM-42BYG011-25.pdf was that it had a current draw of .33A

Well, was able to get it to work. Still lots to do in terms of learning the code and dialing in how I want it to rotate exactly, but certainly appreciate the help. Was wondering about battery power. I just have  a nine volt hooked up to it. I am thinking about either going with a 11 volt lithium polymer to power both the Arduino and the stepper, or just a 2200 Mah NiMH at 11 volts. Figure that should power it for a long time.

I have to say I think I get it now. I have not had a chance to try it all out, but I can see how I can wire the three holes at the bottom. obviously one is ground and the other two just have to go into the digitalwrite ports and then I can just change variables in setup to go to the right pin. It all just sort of came together, at least I think. Just was confused before about some things. Well, after I try it all out I will see how I can distribute the money. I really appreciate the info.

Well at least for now I have the motor wires soldered in. That's a start. Well didn't didn't take a picture of the actual solder but here is the order I put the wires in.

Thanks PaulS. That will help get me started.

I think I have all the hardware I need. Have the laptop the stepper motor, the software, the controller board for the stepper, the arduino. I guess I need to start at square one and learn how to properly use the breadboard and so on. Some of it makes sense. I have a web programming background and as for the motor and electronics fairly well versed in it since I use speed controllers and engines in my hotliner sailplanes, but having troubel seeing how it comes together. I will get it though.

Here is a list of exactly what I have. I will need to get back to you on how the steps would work. I can probably figure out the programming with some minor help, it is just the hook up that I am not sure about.

I have the Arduino Duelinove and a stepper controller. Along with a stepper motor. I would like to pay someone $100 dollars to hook up all the parts and then right a small program. I am modify the program I am sure, but basically want to make a stepper motor rotate 36 degrees, then stop, then turn left and the right and then repeat. Basiically that is all I want to do.

If interested, let me know.

Thanks

I have a Arduino and I have a stepper motor controller. I want to at some point put the stepper  motor controller onto a breadboard and just use those wires with the pins on the end.

Does anyone know where you can get just the pins that you would solder onto the stepper controller board so you can punch it down into the breadboard? Radio Shack didn't have them nor know what I was talking about. Although they did sell breadboards.

Well, it moves the stepper without a problem. It just doesn't seem to have any strength. I can stop it just with a pinch of the fingers.

No no, I am hooking up the car battery to the stepper controller board.

I am wondering if might need a different stepper motor. I have put 12 volts to mine from a car battery and it still does not seem to be able to turn the shaft when I have the load I put on it. Which all that is attached to the shaft is a gear like device weighing less than an 4 grams and then I attach about 1 ounch of aluminum sheet that is about 1 foot long and about an inch wide.

Could I possibly need a different stepper and or more juice. The stepper I am using is the following: http://www.sparkfun.com/products/9238

Thanks for that info. I definitely know I have to be careful not to exceed the motor and controllers specs.

Appreciate the response.

I have a stepper motor and it does not seem to turn with the load I have put on the shaft. Its not much, but the only question is, does pushing more volts to the stepper make it able to handle a heavier load or turn heavier things?
