Right now, I am using all the pins of a three pin potentiometer, in order to feed a signal into a transistor for amplification.
The leftmost pin is GND, the middle pin is the signal and the rightmost pin is what goes to the base of the BJT.
I want to create a PCB board. How do I trace the signals to the potentiometer? Exaclty just I described?
My fear is that I will design the board, but then I will buy and solder a potentiometer with completely different pinout.
So my question is, is the pinout of all the potentiometers the same?
