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 ...

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 ...

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: ...

To use a dark sensor instead, connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output ...
