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 ...

Below is the circuit diagram for this project: The LDR Sensor Module we're using has three pins: VCC, GND, and DO. This module outputs a digital signal, which is sufficient for our needs. We connect ...
