Intro: Arduino - Photo Resistor Example - KY-018
I made another example for one of my sensors. Now we are using the KY-018 Photoresistor Sensor as a switch
to turn on light when shining some light on it, in the video i turn the light on with a laser, a flashlight, a candle, and a lighter, it doesnt matter what kind of light you use.
