| Aug 29, 2020 at 7:23 | comment | added | Oskar Skog | You need to use a PNP transistor (or P-MOS) to do high side switching. The voltage on the base is 0.6 volts higher than the emitter and the diode has the same voltage drop. In order for this circuit to work, the Arduino would need to output 1.4 volts higher than the supply. | |

| Mar 11, 2020 at 1:08 | comment | added | GMc | Mostly because I want to try to get this idea to work. But also because the low power sleep mode, from what I read, is not so low power in an Arduino. As I understand it, sleep mode only puts the Microcontroller to sleep. The USB controller and power regulator are still operating and consuming power. | |

Clarified the explanation in one of the test cases.
