PC817 Optocoupler IntroductionHow PC817 Works?PC817 ExamplesPC817 Optocoupler FeaturesSpecificationsPC817 ApplicationsThe workingof PC817 is very simple but to use it with different devices comes with specifications. The optocoupler at input requires current limiting one resistance but at the output, we will need to connect the logic output pin with the power pin. Whenever the IR signal will be generated at then the logic state will be changed from 1 to 0, due toSee more on microcontrollerslab Instructables
