Hello, Will placing an ammeter in series along the positive end of my power supply tell me how much current my circuit requires? Seems like it should, but my thumbs are green when it comes to actually doing EE. Thanks for taking the time to enlighten me. +5V ---> Ammeter ----> +5V terminal of circuit Regards, Donovan -- http://www.piclist.com hint: The PICList is archived three different ways.
