I have purchased the Arduino Duemilanove and the Easy Driver v4.2, along with the Sparkfun stepper motor. I viewed your earlier tutorial on the v3.1 and wonder if you can help me with some code on the new ED v4.2. I would like to enable the pin that shut off the current between steps. I need 40 steps per rpm with about 12-15 seconds between steps which would be controlled by a limit switch. I also want to shut down permanently after the 40 steps and wait for a power on command to repeat the 40 steps again. All steps are in the same direction. I wired the pins on a breadboard exactly as you did for v3.1, but of course that does not utilize all of the new controls in v4.2.<br /><br />Thanks for help at least in v3.1.<br />Regards,<br /><br />KenAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4933295803079622480.post-66308168560781786042010-01-14T20:12:27.031-08:002010-01-14T20:12:27.031-08:00Hey Dan,

Like the http://vimeo.com/3978871 one. I am hoping to make a repstrap machine with the easydrivers, and it would be cool if you could make it easier. :)keen101https://www.blogger.com/profile/01667843078512519397noreply@blogger.comtag:blogger.com,1999:blog-4933295803079622480.post-2254539628335053972009-11-16T12:26:44.150-08:002009-11-16T12:26:44.150-08:00Hi there,

For now I would recommend following the notes on Brian's Easydrive page. He has a great Q and A section that has been updated recently. <br /><br />Beyond that, I would recommend either the sparkfun or Arduino forums or if you get really stuck, email Brian. <br /><br />Good luck with your course and you projects!<br /><br />Dan.Dan Thompsonhttps://www.blogger.com/profile/09932336949749833460noreply@blogger.comtag:blogger.com,1999:blog-4933295803079622480.post-71636810711535796512009-11-16T11:35:02.043-08:002009-11-16T11:35:02.043-08:00Hey Dan,

I have used your sample code, however my results are not in line with yours. The motor runs differently every time the code is uploaded to the Arduino. <br /><br />ThanksAnonymousnoreply@blogger.com
