How to Wire a Photocell to Multiple Lights?

The terms "photocell" and "photoelectric cell" are often used interchangeably to refer to the same light-sensitive device, such as a cadmium sulfide (CdS) photocell. Both terms describe a semiconductor component that changes its resistance or conductivity based on changes in light intensity.

Using a Photocell | Photocells | Adafruit Learning System

Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don''t wear out. For that reason they often appear in toys, gadgets and appliances. This guide will show you how they work, how to wire them, and give you some project ideas.

Photocell : Types, Circuit, Working and Its Applications

In the lighter scenario, the photocell resistance is maximum and the current flow direction gets modified. So, at the transistor base, there will be minimum resistance. When the transistor''s base terminal receives power, then it operates such as conductor and the path that consists of a resistor, LED1 and transistor will be in OFF state and LED …
