Too Long; Didn't Read
There are many explanations of how a <a href="https://hackernoon.com/tagged/pid" target="_blank">PID</a> works, many of them fantastic. The main issue comes down to how it is explained. I tried to pick up the idea of PID equations when I was much less knowledgeable on <a href="https://hackernoon.com/tagged/mathematics" target="_blank">mathematics</a> and struggled very hard to find a tutorial that didn’t explain it with notation I understood. Symbols are scary, okay?
