TTL OR using BC547 Transistors - Proteus Simulation @budatechnolog

TTL OR Gate Simulation in Proteus | Basic Electronics with BC547 Transistors

In this video, we simulate a **TTL OR Gate** circuit using **BC547 NPN transistors** in **Proteus** software. This practical simulation shows how transistor-level logic works, helping beginners understand the fundamentals of digital circuits without using logic ICs.

🔍 **What You’ll Learn:**

* How an OR gate functions using transistor-transistor logic (TTL)
* Building and simulating the circuit in Proteus
* Logic behavior demonstration (output is HIGH when any input is HIGH)
* How to use basic components to create logic gates

🧰 **Proteus Components Used:**

* 2 × BC547 NPN Transistors
* 2 × Push Button Switches (Inputs)
* 2 × 1kΩ Resistors (Base resistors)
* 1 × 220Ω Resistor (LED current limiting)
* 1 × LED (Output indicator)
* 9V DC Power Source

🎯 **Perfect for:**

* Beginners in electronics
* Students learning TTL and Proteus simulation
* DIY hobbyists and logic gate explorers
