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 between that pin and GND. Pick the fixed resistor close to the LDR resistance under your lighting, then read the pin with analogRead().
Can it measure exact light levels?
No. Its response is non-linear and slow, so it suits detecting light or dark and relative brightness rather than precise lux measurements.
