How to LEARN and USE quaternions

Resources for learning quaternions and applying them for PID control. It also includes a simulation of a direct quaternion PID controller I made.

This was a bit of a different format than what I've done before; I hope it was helpful! In the coming months, I'm planning to have more updates regarding the rocket I'm working on, so stay tuned!

I honestly don't know why YT recommended me this video, but now I know how to learn and use quaternions.
