How to use a photoresistor with an Arduino

How to use a photoresistor with an Arduino In this video we look at using LDRs photoresistors with an Arduino.
They can be setup as part of a voltage divider circuit and act as either a simple onoff switch or as a PWM driver. Heres the Arduino sketch: Light Dependent Resistor 5 mm GM5539 5539: 5mm Diffused LED Diode Assortment: Arduino Uno R3: Male to Male Dupont Cables: Arduino breadboard holder: HEY YOU ABOUT TO POST SOMETHING STUPID: Yes I know my hands are largefat.
Its because of a heart condition I suffer from called Congestive Heart Failure.
Heres a link to some information about CHF: One of the symptoms is that is causes fluid retention mostly in the hands feetankles and face. It will kill me one day.
Im doing ok right now but someday... -------------------------------------------------------------------------------------------------------------------- If you are shopping for electronic components test gear or consumables please consider visiting my Amazon shop amazon.comshoplearnelectronics Please check out www.patreon.comlearnelectronics and pledge a dollar if you can.
It will go a long way to keeping the channel alive.
It costs a bit of money to buy all the items and produce these videos.
