    • Hey there 👋!

      Woohoo! 🎉 You’ve made it to the final part of your learning journey – great job!
      In this course, we’ll explore how computers "think" using just 1s and 0s (yep, only two numbers!) and how they make smart decisions using logic gates – kind of like how we make choices every day!

      You’ve already finished two awesome courses, and this one is going to be just as fun and cool! Let’s get started! 🚀

      By the end of this course, you’ll be able to:

      • Recognize basic logic gates.
      • Build and understand truth tables.

      • Applies Boolean logic to real-world scenarios 💡.

  • What are Logic Circuits? 🤔

    • Think of logic circuits like tiny decision-makers inside a computer. They work using only 1s and 0s (that’s called binary), and they help the computer decide what to do next — just like how we make decisions based on "yes" or "no."

      These circuits are built using small building blocks called logic gates.

      Even the brain of the computer — the CPU (Central Processing Unit) — is made up of thousands of these logic gates working together.

      Now, depending on how they’re used, logic gates come in two main types:

      1. Basic Logic Gates
      2. Combinational Logic Gates

      Let's dive into deep, watch this below video🎬!

  • Constructing and Interpreting Truth Tables 📊

    • Now that you’ve met the logic gates, it’s time to learn how to predict what they do in every possible situation. That’s where truth tables come in!

      A truth table is like a cheat sheet that shows all the possible input combinations (using 1s and 0s) — and the output that comes from them.


      👉 Let’s find out what Boolean expressions are and how we can turn them into truth tables. 🎯 Watch the video below to learn step by step🎥.

  • Practical Usage of Logic Gates

    • Ever wondered how your computer knows when to unlock, or how a traffic light changes at just the right time? 🤔
      Well, behind the scenes, it's all thanks to logic gates!

      In this lesson, we’ll explore how these small but powerful gates are used in real-life systems — like alarm systems, calculators, and even your smartphone📱!

      Circuits designed to control streetlights💡

      There are several occasions when the lights are on. These are,

      • When only the manuals switch is closed 
      • When the input of the timer is 1 and when the environment is dark.

       If the time is in the range of two pre-arranged ranges the input is 1 and 
      otherwise 0. This means, the input is 1 when time is from 6 pm and 6 am, and the input is 0 when from 6 am to 6 pm. Further, the light sensor will be 1 when there is light above pre arranged value and it will be 0 when it is dark. When the environment is gloomy with a rain cloud, the street light will not be on though the light sensor’s value is 0 if the time is not between 6 am and 6 pm.
