How to Make an Automatic Light Using LDR (1W LED + Battery) — Simple DIY Guide
What you’ll build (quick) A compact, battery-powered automatic light using LDR that turns a single 1W LED ON when ambient light falls below a threshold (night) and OFF in daylight. The circuit uses an LDR as the light sensor and a small logic-level N-channel MOSFET as the switch to handle the LED current safely and
