A basic setup for a NOT gate using transistors.

A NOT gate is also known as an Inverter as it inverts the signal from being a HIGH to LOW or from LOW to HIGH.

Below you will find the circuit schematics and list of parts for this setup, and also a video showing step by step how to build the circuit on breadboard.
