The user can choose whether to use the circuit as the light or dark sensor. The same output can be used to drive an LED, indicating the detection of light or dark. A photoresistor can be paired with ...

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 ...

Here three LDR sensors are used to control the brightness of individual Red, Green and Blue LED inside RGB Led. Learn more about controlling LDR with Arduino here. There are two types of RGB LEDs, one ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy ...

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 ...

In this circuit, we are making a Light Sensor using LDR with Arduino to control a bulb/CFL as per light condition ... Here, we are defining the Pins for Relay, LED and LDR. #define relay 10 int LED = ...
