This Light Sensor Snaps On and Off | LM393 Explained

This is not a night light. This circuit makes a clean decision using a comparator. Light crosses a threshold, and the output snaps ON or OFF. In this video, we build a light threshold detector using the LM393 comparator. Unlike simple LDR + transistor circuits that slowly fade, this design compares two voltages and makes a clean digital decision. When the light level crosses the set point, the output switches instantly. This is the same core idea used in: • solar garden lights • line-following robots • light alarms and daylight switches • industrial sensor inputs No microcontrollers. No code. Just fundamental analog logic.
