Bipolar Junction Transistor (BJT): What is it & How Does it Work? | Electrical4U

If your Logisim projects are starting to look messy and hard to follow, this lesson is for you. We’ll walk through what a sub-circuit is, why it matters, and how to turn a simple design into a reusable block you can plug into bigger systems. The focus is slow, clear explanations so you actually understand what you’re doing, not just copying. By the end, you’ll know how to keep your digital logic projects structured, readable, and easier to debug. | Engineer Thileban Explains
