    A light sensor (LDR or Light Dependent Resistor) is a simple component that provides a variable resistance that changes with light, which we can read into the Arduino board as an analog value. This Light sensor module uses a LDR to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases.

    You can download the Starter Kit Guidebook Experiment 11 - Read the Light Sensor and related source code to learn how to use this module.
