A micro stepper motor for sale driver such as the A4988 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels.

Sam,

I can send it to your email, and you may need to download a pay apps in iphone too.

Kenneth,

I am very interested in your Robot Arm project, I also want to build a robot arm being controlled by iPhone. would you mind sharing the source code and drawing?

Thanks for the link.

Don't worry about the stepper motor side, I'll help you with that.

Please send it to happytriger2000@gmail.com

Not much, but I just know that I can precisely control the turning angles and number of turns. By the way, you wanted the tutorial on the robot script? I put it on web http://kennethportfolio.weebly.com/grasshopper-projects.html

Where you want me to give you the source code? You may need a number of plugins being installed first.

This might be what you needed:

How much do you know about Stepper motor?

"That's great. I was also thinking about using the stepper motor instead of servo.

@Kenneth,

              Is up to you if u want to use stepper, but in Automation industry, usually is AC servo.

"Do you know is there any code existing that can replace the use of a stepper motor controllor?""

Are you trying to use Arduino as a stepper driver? If so, then you need coding for that and is much harder, search Arduino forum, I'm not really good at coding.

I'm thinking of using iphone to control my RM-501....would you mind sharing the grasshopper and firefly definitions?

Give this a try, turn RC servo to DC servo.

Hint: http://danthompsonsblog.blogspot.tw/2010/05/easydriver-42-tutorial....

take the code from D. Thompson, I've tried the code worked great:

for the same code it will also work for a DC servo driver:

then you can run this robot (Mitsubishi RM-501) like you have there in the video but slight different in size and accuracy: http://youtu.be/meso-Wmbd_E

Great job by the way.

Love it, that looks so fun. You should make it build a LEGO set
