The Field Effect Transistor (FET) has only one input which is the "Gate". Depending on whether the FET is a P-channel or N-channel type will determine how the Gate electrode controls electricity between the "Drain" and the "Source". Here is a video that describes how a FET works in detail: How FETS Function

OOPS! I see that you made a change to this scene which is not correct. You labeled the FET transistor "PNP" which is a type of "bipolar" transistor, NOT a FET which is what you had drawn.

No offense, but maybe you should learn about transistors before trying to teach others about them.

I'm not trying to teach about how a transistor works, but just make one that doesnt require scripting and can also perform a logical operation as fast as possible.
I will make the neccessary changes to the scene, and thanks for letting me know!

No problem! I'm sure the scene will be very interesting.
