Attached is a picture of a schematic.
My question is: let's say the current rating for the LED is 20mA and the forward voltage is 2.7V (max.)
Looking at the schematic, there is 5V before the LED and 2.62V after the LED before the resistor. Which number should I go off of, if I'm trying to make sure I don't burn out the LED? Do I need 2.7V before I reach the LED, or is this scenario okay?
