Hey Everyone, I'm relatively new to arduino hardware and programming, and I am trying to get a project going using muscle wire and an arduino. I have read a great deal of the questions posed in the forum regarding SMAs and am currently making my shopping list. I intend on using thin SMA wire, from .0015-.003 mm in diameter, 2 to 3 inches in length. I realize I will need something to suppliment the current that comes from the arduino pin, one of the projects in the forum uses this kit...http://www.sparkfun.com/products/10256 paired with an external power source.I am not sure what I should use for the external power source- or how many volts it should be. If someone could make a suggestion for this, that would be great ( a link would be amazing). I also realize that I will need a resistor, I have a bunch of these so when I calculate the necessary resistance I am confident I will have something that works. Is there anything glaring that I might be missing here?
Ideally I want to hook up a small sensor to the arduino for control, but would just like to get it going first. Are there any really in depth tutorials available online, I have found this http://makingfurnitureinteractive.wordpress.com/category/course-materials/page/2/ which certainly helps, but does not quite answer all of my questions about wiring with arduino.
