Ldr circuit

Dark Sensor With LDR, Transistor and a LED: You wan't do a dark sensor with a LDR, one transistor and one LED and you don't know how to do it? In this small tutorial I will explain to you how you can do that even if you know only the basics of electronic. Parts you need: 1 Breadboard; 1 Pow…

This circuit has many applications. It could act as a photocell and switch off a light in a room or turn on the radio when it is dawning, etc.

This Laser Security Alarm Circuit uses two BC548 NPN transistors as a switching device. Since the LDR is connected to the base terminal of

Learn how to make a Circuit that can Switches OFF the LED when LDR senses darkness. This circuit is an opposite type of LDR night ON and day OFF circuit, in which LED switches ON when LDR Senses dark. I hope this LDR, LED and 555 timer IC breadboard tutorial will be helpful for you!

A photoresistor or LDR (Light Dependent Resistor) as the name suggests will change it resistance based on the light around it.

#LDRCircuit is a variable resistor whose value decreases with increasing incident light intensity.

This simple LDR circuit diagram shows how you can use the light dependent resistor to make an LED turn on and off depending on the light.
