What will I learn?
The Photoresistor Course gives you practical skills to design and validate reliable LDR circuits fast. You will learn LDR fundamentals, voltage divider design, transistor switching, and precise comparator thresholds, then verify behavior with Falstad or LTspice and real measurements. Step-by-step examples, safety tips, and troubleshooting guides help you build stable light‑controlled LED and buzzer applications with confidence.
