Transistor Logic Basics: OR, NOR, XOR & XNOR (Part 2 of 2)

In this video, we build and explore four essential logic gates using transistors: OR Gate NOR Gate XOR Gate XNOR Gate You’ll see how each circuit works on a breadboard, how the inputs affect the output, and why these gates are fundamental to digital electronics. This is a hands-on, beginner-friendly walkthrough designed to help you truly understand—not just memorize—logic circuits. 00:00 Introduction 00:28 Inverter 02:28 Buffer 03:23 AND Gate 05:03 NAND Gate 08:22 OR Gate 10:59 NOR Gate 13:57 XOR Gate 22:13 XNOR Gate 32:04 To The LAB! 32:09 OR Gate LAB 35:34 NOR Gate LAB 36:47 XOR Gate LAB 39:26 XNOR Gate LAB 44:30 IC Introduction 50:22 Bible Verse 🌐 Full video notes, diagrams, and explanations: 👉 https://buildcircuitswithrich.com 👋 About Me I’m Rich, an electronics technician and engineer passionate about helping beginners learn circuits the simple way—by building and understanding real hardware.
