How to Make a Photocell LED
A photocell is a semiconductor device that is sensitive to light. Different types of photocells are available. The most common are the ones that produce current when subjected to light. Solar panels that are used to produce electricity are made up of...
It's a small easy to build circuit that will, as the title says, turn an LED on when it's
