🔍 Can we use Switches to Make a Choice!?

We now know that switches can turn electricity ON or OFF. That’s great for sending messages. But what if we want a machine to make a choice?

👉 What if we want to say, “If A is ON and B is ON, then turn the light ON”?

That’s where logic begins.

 

🧩 Logic Is Just Clear Rules

In real life, we make choices using logic every day:

• “If it’s raining AND I forgot my umbrella, I’ll stay inside.”

• “If I’m hungry OR it’s lunchtime, I’ll eat.”

Computers do the same thing—but using electricity.

They use logic switches to do this. These are tiny electric parts that follow exact rules.

 

⚙️ The Three Basic Logic Rules

1. AND – “Only turn ON if both are ON.”

2. OR – “Turn ON if one or both are ON.”

3. NOT – “Do the opposite. If it’s ON, turn OFF.”

Just these three rules let computers make choices, follow steps, and do math.
