Arduino Uno: The microcontroller board used for processing sensor data and controlling the robot.; LDRs (Light Dependent Resistors): Sensors used to detect the light intensity. Motor Driver Module: ...

It’s like Dark and light Detector circuit but this time we are using Arduino to get more control over light. In this circuit, we are making a Light Sensor using LDR with Arduino to control a bulb/CFL ...

You can learn more about PWM in Arduino from here. How it Controls the Light Intensity Automatically: As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor.

A light-dependent resistor (LDR) whose resistance is inversely proportional to the intensity of light is often used as a sensor in electronic projects that involve the use of light. This LDR based DC ...

Control everything with a DAC, and you have a programmable load controlled by an Arduino. With such a small form factor, getting rid of all that heat was bound to be a problem.

Arduino is used for controlling the light at the transmitter side. At the receiver, the photodiode or Light-Dependent Resistor (LDR) changes over the received data into original information. A working ...

The proposed system is implemented using a GSM shield module on microcontroller (Arduino®) together with LDR sensor and relay. Existing metering system can be minutely modified to implement the ...

Welcome to the Light Following Robot project repository! This project demonstrates how to build a simple yet effective light-following robot using Arduino and Light Dependent Resistors (LDRs). This ...
