But seriously, I don't think turning off both LEDs and have independent currents while power is on is doable with one IO pin without extra components. Easy with two IO pins, though. | |

| Nov 24, 2020 at 19:23 | comment | added | Hearth | @BeB00 That could be considered a feature! Set the pin to input if you want to turn on both LEDs. | |
