Hi Rocky,

I just looked at 'Arduino'.................  All I can say is that the
stuff would seriously BEND my brain for a very long time!!!

I am sure that what is needed, could be done somehow done with the
Arduino but this project will need to be simpler to install.

Thanks for the tip, but that is VERY Scary!!!  :-)
