LDR Module: The LDR module consists of an LDR sensor that detects changes in light intensity. It converts the received light signals into electrical signals that can be processed by the Arduino Uno.

Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver module for control. By building this simple light following robot you will learn the ...

A model of a utopian traffic system was designed using Arduino as the microcontroller, LDR, LM393 sound detection sensor module and HW-201 1R sensor. Sensors used: HW-201 infrared (IR) sensor, Light ...
