Connecting a motor to an HMC5883L type magnetometer

Hi guys saw a video from 7 years ago, I need this code for my thesis. I am making a wind turbine and I need to make it rotate depending on the wind. I have an arduina uno and I need code that can do what the video shows. The author of the video doesn't answer yet

Please read the topic "How to get the best out if this forum."
Please collect facts and data from that video and present it here.
The intention of forum is to help members learn and grow in programming. Is not a free code factory giving away ready to use touys. The helpers work for free.

I'm a newbie I can't find any forum with the code I need (

You need to start learning programming. Most likely the code You want does not exist anyware.
There is a section where You can pay for coding. However the project needs to be well specified.

Please read the forum guidelines. That page will tell you some of the things that we need to know to be able to help you.

I will not sit through a video and try to figure out what you want.
Please describe, in detail, what it is that you want to happen step by step.

What parts do you have? Provide data sheets or links to where you got the parts.

Post a wiring diagram. Hand drawn, photographed and posted is fine. Include all pin names/numbers, components, their part numbers and/or values and power supplies.

What have you tried in terns of writing the code? Post your best effort. Tell us what the code actually does and how that differs from what you want.

Do not power the servo from the Arduino. For reliability, an external power supply for the servo is required.
