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.

In this tutorial, we will use one such sensor BH1750 Light Sensor Module and interface it with Arduino and show the Lux value over 16x2 LCD.

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 ...

Light Sensing: The system uses a light sensor to detect the intensity of ambient light. Automatic Lighting: Based on the sensor readings, the system can turn lights on or off to maintain optimal ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

This project describes a simple Arduino-based digital light meter, which is capable of measuring the ambient light intensity ranging from 0-65535 Lux. The output is displayed in both Lux and ...

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 ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...
