Course content

2 sections • 6 lectures • 30m total length

Welcome to Boolean City4:49
Step into a world where every decision is made by mysterious gates. Learn the basics of 0s and 1s, True and False, and why Boolean Logic is the heartbeat of every computer.
Meet the Gatekeepers6:28
Get introduced to AND, OR, NOT, NAND, and XOR gates. We’ll explore how each one thinks, their unique “rules,” and how they combine to create powerful decisions.
Truth Tables: The City’s Rulebook4:29
Master the skill of creating and reading Truth Tables. You’ll practice predicting outputs for any gate combination and understand the “laws” of Boolean City.
The Security System Mystery2:58
Tackle a real Boolean City case: a security system that only opens under specific conditions. Build its Truth Table, write the Boolean equation, and solve the puzzle.
The Grand Circuit Challenge3:08
Your final mission—analyse a multi-level circuit with multiple gates. Use your skills in Truth Tables and Boolean Algebra to crack the code and graduate from Boolean City.

Quick Recap of Logic Gates & Truth Tables Made simples and Circuit Design8:16
In this review episode, you’ll revisit the streets of Boolean City one last time, consolidating everything you’ve learned. From AND Street to XOR Bridge, every Logic Gate will be brought back into focus through quick recaps and practice challenges.

? In this session, you’ll:

Review the core meaning of Boolean Logic.

Revisit each Logic Gate (AND, OR, NOT, NAND, NOR, XOR) with fast analogies and examples.
Practise converting Logic Statements → Circuits → Truth Tables.

Test your understanding with real-world scenarios like traffic lights and security systems.

? By the end of this review, you’ll be fully prepared to unlock the gates of Boolean City and apply logic with confidence.

Requirements

No prior programming or electronics experience needed
A basic understanding of numbers and simple math is helpful
Curiosity and willingness to learn logical problem-solving

Description

Imagine walking into a hidden city where every door, light, and alarm is controlled by mysterious gates—each with its own unique rules. This is Boolean City, where you’ll embark on an unforgettable journey to master the heart of computer logic.

In this course, you won’t just memorize formulas—you’ll experience Boolean Logic as part of an ongoing adventure. Through engaging storytelling, hands-on examples, and real circuit designs, you’ll uncover how computers “think” and make decisions.

From basic logic gates to complex circuits, from truth tables to Boolean algebra simplification, every lesson is crafted to be clear, memorable, and fun. By the end, you’ll have the confidence to read, design, and simplify logic circuits like a pro.

Whether you’re a computer science student, a coding enthusiast, or someone preparing for exams, this course turns abstract concepts into concrete skills you’ll never forget.

You’ll practice building real-world logic scenarios such as security systems, alarms, and control panels—then break them down into Boolean expressions and truth tables. You’ll also learn to spot and fix inefficient circuits, making them faster and more cost-effective.

By combining theory with storytelling and challenges, this course ensures you not only understand Boolean Logic but also apply it with confidence in academic, professional, or personal projects.

Who this course is for:
