How do I read this LDR with an Arduino?
Build a voltage divider: connect the LDR between 5V and an analog pin, and a fixed resistor (for example 10kΩ) between that pin and GND. Read the pin with analogRead(). Choose the fixed resistor close to the LDR resistance under your typical lighting.
Can it measure exact light levels?
No. LDRs respond non-linearly and slowly to light changes, so they suit detecting light or dark and relative brightness rather than precise lux measurements.
