OR Gate TTL Using BC547 Transistors @budatechnolog

🟥 OR Gate TTL Using BC547 Transistors – Logic Gate Tutorial | Buda Tech

🔧 In this video, we demonstrate how to implement a TTL OR Gate using BC547 NPN transistors. This simple yet educational project helps you understand the working of OR logic using basic components like resistors, transistors, switches, and an LED.

📌 What you'll learn:

* The logic behind an OR gate (output is HIGH if any input is HIGH)
* How to build the circuit step-by-step
* Circuit operation using transistor logic (TTL)
* Practical demo with a glowing LED as output indicator

💡 Components used:

* 2 × BC547 NPN Transistors
* 2 × Push Button Switches
* 2 × 1kΩ Resistors (input resistors)
* 1 × 220Ω Resistor (LED protection)
* 1 × LED
* 9V Battery

📘 **Use Cases:**

* Great for beginners in electronics
* TTL logic gate learning
* Project for electronics students and hobbyists
