I want to implement the following very simple logic:
Voltage at point "A" is high ==> LED is OFF
Voltage at point "A" is low or floating ==> LED is ON
and I came up with the attached circuit to implement it. I'm just wondering if there is anything "bad" about doing it this way, or if this circuit is OK.
