The photoresistor sensor module includes a LDR (light-dependant resistor) in series with a 10K resistor. The AO pin is connected between the LDR and the 10K resistor. The voltage on the AO pin depends ...

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.
