One advantage of the Arduino as an EMC2 I/O expander is that a lot of work has already been done. http://axis.unpy.net/01198594294 Actually, I suppose the Arduino could do the whole app. alone. I think it has a simplified programing language that tries to bring micro-controllers to nontechnical types, but I really haven't looked into it. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Forrester recently released a report on the Return on Investment (ROI) of Google Apps.
