I have the Wemos D1 R2 ESP 8266 board and I've discovered that the HIGH and LOW outputs are all inverted. This was fine at first but I'm trying to run a servo (the servo is running on its own power source) but it just buzzes when plugged into the pin. I set the pin to LOW at the start of my loop because I thought that when the servo was called, it would change the pin to what it needs but the servo just buzzes when its called.
Does anyone have any ideas of why, how to possibly invert them back, or simply, how to make the servo run properly?

I've tried all of the pins and none of them work with a servo though. Even if the servo isn't being called as soon as the servo touches the pin, it starts buzzing but doesn't move.

OK, so your code is wrong.
Alternatively, it may be that the servo is reacting unfavourably to the 3.3 V logic levels.
