Need urgent troubleshooting to finish project! Servo will not run on Wemos D1 R2

I am working on a school project with the D1 R2 and I noticed that all of the pins outputs are inverted, I know there are pull up and pull down resistors in place but I've tried all of the pins and they all seem to be this way. It was fine for everything else because I just reversed the HIGH and LOW but I really need a servo to work. If I assign the servo to a pin, as soon as I connect the serial pin, the servo starts buzzing but never moves. I have tried with an external power source and directly on the board with no luck. I can send money through pay pal or something, I am desperate, I really really need this project completed right away.

Hi,

I can help you. Please check PM.

It's clearly the green wire. Please doublecheck it.

Green wire as in the ground? I've moved it to all the ground pins on the board and when I had it hooked up to the external power source I connected the ground to the board.

You did not connect it to the flux comperator for initialisation?

OP, please do read up on the flux comparator as mentioned above. It'll really be helpful.

By the way, I think it's the pink wire, it's clearly curled up in the wrong direction.

How am I using the forum wrong?

You have left out almost every important detail that would allow people to help you, hence the comedic answers.

What model of servo? How is everything wired up? What's the external power supply? What code are you using?

You obviously didn't read the link I provided, or you would have known.
