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.

To use a dark sensor instead, connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output ...

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 ...

USING AN LDR SENSOR WITH ARDUINO Introduction 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 ...

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 ...

The output of the whole circuit is given by the buzzer so, the positive pin of the buzzer is connected to the pin 12 of Arduino and the negative pin is connected to the ground of the ultrasonic sensor ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

The Arduino board in connected to an LDR (Light Dependent Resistor) sensor that captures the light reflected from the mirror which was emitted by a single LED. The ruler will be manually set in motion ...
