🔍 Why This Matters
Single gates (like AND or OR) are like single thoughts. But real decisions often need many thoughts together.
Let’s see how we can combine gates to do more complex things.
🧠 Example: A Door Lock
Imagine a digital lock that should open only if:
-
The person entered the right code
-
AND it’s daytime
-
AND the battery has charge
That needs three AND gates chained together.
🔁 Example: A Smart Light
Turn ON the light if:
-
It’s dark OR someone walks in
-
BUT only if the switch is NOT off
That’s:
-
OR between “dark” and “motion”
-
AND with “switch is ON”
-
AND a NOT gate for “switch is OFF”
See how logic blocks can be stacked like Lego pieces?
This is how all decisions in computers are made.
🔍 Why This Is Powerful
With just these blocks, you can:
-
Do math
-
Check passwords
-
Play music
-
Run games
Everything in a computer starts with just switches—and rules.
