Hi! I'm experimenting with the Arduino and I'm on the "analog input" page :slight_smile: I just can't understand how actually the analog input works from an electrical point of view. So, the default reference is 5v and that's read to 1024, but how it actually "feels" the voltage applied on the pi…

how analog input works? (from an electric point of view)
