With a little more thought, a dual frequency detector, for "open" and "closed" would be needed. Or an AC pump and DC level detector. A software DTMF decoder component would allow for more states to be detected. ------------- Kirk http://www.wallacecompany.com/machine_shop/ ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
