Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light intensity using the LDR sensor. Based on the detected light level, ...

Hi Everyone, This is my 1st Arduino's tutorial video. In this video i am going to show you how to use a LDR or Light Dependent resistor to turn on and off another circuit or a LED. Wouldn’t it be ...

This dark activated switch can trigger a relay to operate an AC lamp at Sunset. The lamp remains on till morning and then turns off. This eliminates the need of switching the Porch lamp or Backyard ...

A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel ...

This paper focus on the idea of automatic lightning system and peculiar way of implementation with embedded tool systems. The proposed method is used to measure and control the intensity of light in ...
