This is a simple light/dark sensor circuit built on a breadboard. This project is suitable for electronics beginners.
The LED connected to the transistor stays on until the light falling on the photoresistor is blocked.
Learn to build a dark sensor circuit using NE555. It is similar to other dark sensor projects. The project is good for school students.
