What will I learn?

This course equips you with hands-on skills to create and test dependable LDR circuits efficiently. You'll master photoresistor basics, voltage divider setups, transistor control, and accurate comparator levels, then confirm performance using Falstad, LTspice, or actual tests. Guided examples, safety advice, and fix-it tips enable confident construction of reliable light-activated LED and buzzer projects.
