I don't feel offended. I am indeed familiar with electronics, what I dont know for sure are the english terms since I am not a native speaker. If you want a circuit diagram, I can provide one.
Yes I am using a so called Multimeter. But I have to disappoint you, it doesn't matter if with or without, the Blink Sketch starts only with 15V=. Or if I am connecting the USB cable to the 5V recharger of my mobile phone. Setting the power supply to 5V= and connecting it to the special "5V" pin for stabilized input, the sketch isn't starting either.
