Thanks raschemmel,
I ran across an article about the Open Sprinkler project based on Arduino. The author provides a complete tutorial on the project with schematics and parts list. Open Sprinkler is used to open and close multiple water valves. Perhaps there is something in the article that markpeace can use for his project. Markpeace, I would like to know more about your project. Please keep us informed on your progress. Thanks, MT.
