How Circuits Switch Themselves On and Off Automatically Using Transistors

Mechanical switches and buttons work — but what if you want a circuit to turn itself on? In this lesson, we explore transistors, the electronic switches that let tiny signals control large currents — instantly, silently, and automatically. By the end of this video, you’ll understand: What a transistor is and why it’s used How transistors act as electronic switches The difference between NPN and PNP transistors How base voltage controls current flow When to use NPN vs PNP in real circuits Why transistors are essential for automation and microcontrollers This is Lecture 11 in the Horizon Robotics Lab Electronics Series — a beginner-friendly course focused on intuition, real-world examples, and hands-on learning. 👉 Want to build these circuits yourself?
