Hi, I am very new to Arduino.
I just purchase a stepper motor (http://www.robotshop.com/PDF/rb-soy-07-unipolar-stepper-motor-specs.pdf or http://www.robotshop.com/rbsoy07-soyo-unipolar-stepper-motor.html) and Easy Driver V4.2 to make an exactly same stuff what this person made (Dan Thompson: EasyDriver 4.2 Tutorial).
Please let me know which wire color (B, Y, G, R, W, and B) goes to A,B,C, and D in the first picture of this (http://4.bp.blogspot.com/_POxG6aoXG3o/TAsyGBniZBI/AAAAAAAABLQ/X6nFqJ1TOAg/s1600/ED4_revised.jpg) and which two wires are not connected to anything in the blog.
The motor works with 12V which is different from Easy Driver voltage 5V. Do I need to put anything to control (decrease) the voltage? Also, this is unipolar. I found that some tutorials for the Easy Driver recommend using Bipolar. Can I still use my motor?
Please let me know anything I should keep in mind not to burn Arduino, Easy Driver, and a motor.
Any advice and answer is very appreciated.
