Hi, i just make a small circuit which detects electromagnetic fields using mosfet and BJT transistors, I just bought the pieces and i am waiting for them to start testing at the real life, so advancing in my report i downloaded fritzing to draw my project, after i finished drawing all seems to be good, instead of the 1 gigaohm resistor, i don’t know what’s that weird connection, can anyone help me? the schematic and the breadboard prototypes are in the file .fzz, I’ll also add an image of my original circuit. thank you.
