I am about to start a class in low voltage, was not presented with more info then low voltage. I have done a couple searches on low voltage, ac/dc low voltage but nothing comes up as like a tutorial or intoduction to low voltage. just wondering if i am missing something more then low voltage is there more to it in the name? i found a site called all about electronics and they have tutorials on alot of electronic stuff but nothing on low voltage just wondering if anyone knows of a good site to read on it or get familiar with it before i start my class next week... with the long weekend i wanted to read a little on it. thanks
