WebExposed to darkness, a photoresistor has a tremendous amount of resistance. Depending on the specific photoresistor in use, its resistance can be anywhere from over 100KΩ to well over 2MΩ. When exposed to bright light, a photoresistor's resistance drops drastically. Again, based on the photoresistor, it may be to 5KΩ or below or to about 30KΩ. WebLight Level Find the light level (how bright or dark it is) where you are. The light level 0 means darkness and 255 means bright light.
