When constructing the sensor, consider these things. The LDR should only be exposed to the reflected light from the surface which was emitted by the RGB LED. Light from the RGB LED should not directly ...

In this circuit, we are making a Light Sensor using LDR with Arduino to control ... Complete Arduino Code and Demonstration Video is given at the end of this project. Here, we are defining the Pins ...

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 ...

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 ...
