How to use the LDR for measure an ambient light level. A photoresistor (light dependent resistor or LDR) would do a great job of measuring the parameter. A photoresistor is a pretty primitive device, and all we need to do is read its value from the analog port on the Arduino. We will measure a lightness level, and if the values exceed or are below the threshold, we will turn an LED on or off. Cover the photoresistor (the LDR) with your hand, and watch how the activate of the LED.
