What will I learn?

This course equips you with hands-on skills to design and test reliable photoresistor (LDR) circuits efficiently. You'll cover LDR basics, voltage divider setups, transistor switching techniques, and accurate comparator thresholds. Validate designs using Falstad or LTspice simulations plus real-world measurements. Includes step-by-step guides, safety advice, and troubleshooting for building dependable light-activated LED and buzzer projects.
