That’s where the open-collector open drain configuration comes into play like I mentioned in a post above.
Another reason to drive an LED on the low-side(cathode into the microcontroller pin).
Many microcontrollers have open-drain(open-collector) output settings.Basically the pin can be set to behave as a single NPN(NMOS) Transistor. This takes care of voltage translation if the LED is to be driven from a higher voltage then the micro’s supply voltage without having to use an external transistor..
Just thought that was worth mentioning.
