Using the 5v regulator with control, if I wanted to add an LED, do I have to use a separate resistor, or could I just add the LED into hoogie's existing circuit, using the same resistor as the control pin, as in Fig 1?
Or would it be better to do it as in Fig 2? Or would I be better putting it in parallel with the atty (which I would rather avoid). Actually trying to avoid adding another resistor into the circuit at all.
