In this project we are making a Light Sensor using LDR with Arduino to control a light bulb/CFL as per light condition of the room or outside area.

We are going to build a simple Light Sensing circuit or Light Detector using LDR - a resistive light sensor, to control the ON-OFF of the system associated with respect to the intensity of light that ...

This repository contains the implementation of a Smart Street Light Control System using a 555 Timer IC, Light-Dependent Resistor (LDR), and a Relay. The system uses an LDR (light dependent resistor) ...

Night Security Light System – Circuit The circuit diagram of the Arduino-based night security light is shown in Fig. 2. It is built around an Arduino Uno board (board1), PIR sensor connected across ...

This project presents an advance lighting system to minimize the wastage of electrical power and save electricity. For this purpose we are using Arduino, Light Dependent Resistor(LDR) and Passive ...

The output from the LDR op-amp circuit can be used to drive an LED directly or via Arduino. In this tutorial, the circuit has been taken on a PCB, in which the operation as a light or dark sensor can ...

Fig 1. LDR Plus GSM Based Security System Prototype This project will teach us how to make a smart device that can notify us whenever any unauthorised person opens the safe box/drawer. Basically, the ...

Smart Stick For Blind People (Picture Courtesy: Circuit Digest) How To Use Arduino In Designing The Circuit? Now as we know the abstract of the project, let us move forward and gather different ...
