Hello, I have 4 safety switch, however I do not know how to configure them, I have a 3-pin DIP switch goes to GND should give an impulse to say all'arduino stopped the program so I say if the level is high but still stopped otherwise I do not know how to give the impulse all'arduino.
can you tell me some solution
I fear this post is hard to understand (What is a "4 safety switch" ?).
Is it related to your "configuration microswitch" thread ? http://arduino.cc/forum/index.php/topic,111733.msg839383.html#msg839383
Or perhaps it's easier to explain in the Italian forum ?
