Arduino - Photo Resistor Example - KY-018

Hello World!

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.

See the next step for the Schematic Code & parts list.

Parts List.

1. Arduino uno, I used the RobotDyn Uno.
2. KY-019 1 channel Relay
3. 1 Led of any color. I used blue.(Don't really need this)
4. KY-018 Photoresistor sensor.
5. Lamp + socket and power cable (optional) You can an add any device!

Good luck!
