Here is a circuit diagram for a simple logic probe in my digital electronics book I bought to learn electronics on my own.
It says in book when switch is High or Low, only that LED will light, but I'm having difficulty visualizing this. Why can't current flow straight down on right side from +5v to GND at all times lighting both LEDs?
