The Arduino LilyPad Light Sensor is a sensor board with wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPadwas creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!

This is a simple to use light sensor that outputs an analog value from 0 to 5V. With exposure to daylight, this sensor will output 5V. Covering the sensor with your hand, the sensor will output 0V. In a normal indoor lighting situation, the sensor will output from 1 to 2V.
