This method of interfacing an LDR with Arduino is simple, user-friendly, and typically preferred. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by ...

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 ...

Today, we are building a simple Arduino-based project: a light-following robot. This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

In the microcontroller era today, Arduino is ... Here an LDR (Light Dependent Resistor) is used to measure the light level. The alarm system is triggered when a “Logic High (H)” level signal is ...

LDR senses ambient light, and soil moisture sensor senses soil moisture content. Arduino Nano board is used as a microcontroller to read the data from all three sensors and transmit it using RF ...

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 ...
