How to use a photoresistor with an Arduino

How to use a photoresistor with an Arduino
In this video we look at using LDR's (photoresistors) with an Arduino. They can be setup as part of a voltage divider circuit and act as either a simple on/off switch or as a PWM driver.
Here's the Arduino sketch: https://pastebin.com/g8dzETqY

HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: https://cle.clinic/2TdS2Ux
One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face.
It will kill me one day. I'm doing ok right now, but someday...
