Multimeter doesn't work properly
Good evening, I just created a sort of multimeter able to test a little circuit composed by a battery and a lamp.
The main goal is to find the fault (the red wire is in over loop) checking the voltage and the resistance in all the pins.
My problem is about the sequence of the measurement. When I put the "red arrow" for first and the black one for second the program works properly but if I put the black arrow first and the red one later, the multimeter doesn't show me the same layer of the first case.
Attached you can find the file. I need help to resolve it.
Any ideas?
