How do I read an LDR with an Arduino?
Build a voltage divider with a fixed resistor and the LDR, then connect the midpoint to an analog input. As light increases, the LDR resistance drops and the analog reading changes accordingly. Choose the fixed resistor value based on the light range you need to measure.
Can I run it at higher power than 200 mW?
No. The maximum power is 200 mW, so keep the dissipation within that limit by using a suitable series resistor and voltage. Exceeding the rating can overheat the sensor and change its behavior.
