What will I learn?
This course equips you with hands-on skills to design and test dependable LDR circuits efficiently. You'll cover LDR basics, voltage divider setups, transistor switching, and accurate comparator levels, then confirm performance using Falstad or LTspice simulations alongside actual measurements. Guided examples, safety advice, and fault-finding tips enable you to confidently create reliable light-activated LED and buzzer projects.
