How to Use a Photoresistor (Light Sensor) with Arduino (Lesson #27)

Science Buddies Electronics Kit for Arduino: https://www.homesciencetools.com/prod...

Photoresistors, also called photocells or light dependent resistors (LDRs), make great light sensors for Arduino projects where you only need a coarse measurement of light levels. Learn how to use one in this video.
