For this, we need a light sensor to detect the light ... and the light turns OFF. Complete Arduino Code and Demonstration Video is given at the end of this project. Here, we are defining the Pins for ...

This project demonstrates how to build a simple yet effective light-following robot using Arduino and Light Dependent Resistors (LDRs). This robot will autonomously follow a light source, making it a ...

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 ...

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is ...

But a common transparent LED can also be used in the place of an LDR or a photodiode. Here is a simple circuit that uses a transparent red LED as the light sensor that switches on a white LED when the ...

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 ...

MP3 Module (I2C) for MP3, WAV, WMA format audio 8×16 Dot Matrix Module with 8 levels of brightness Touch sensor to light up the LED when touch is detected ... and expansions MechDog open-source robot ...

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 ...
