What is PID and coding PID in vexcode blocks

[RoboticsEli]

My team has been seeing other teams, even sister teams, using PID. I watched a video about what it is in real life, but I am wondering how it ties into VRC. I am also wondering if it is possible to code PID in code blocks because no one on my team knows how to code C++ or python.

See below, a post (originally by @_Colossus) from 2020 I found with a quick search of the forum.

Here is a quick list of PID resources that come to mind:

1. My Basic PID Introduction
2. What is PID?
3. The Fabled PID & specifically this guide
4. Tuning PID
5. Advanced RobotC PID Example

Hopefully this serves as a good springboard for you to continue researching PID resources online as others have suggested. While none of these resources will teach you the entire in’s & out’s of PID alone, if you take the useful information from all of them you should get a very solid understanding of PID.

This would also be a good opportunity to learn C++ or Python! I too had to make the jump from blocks to written code (albeit quite some time ago now) but I’ve never looked back since.

I am currently learning Python, but am only on the basics. I will make sure that me and my team look over these useful resources.

Yes.

For an engineering class, I “wrote” a useable PID in block code. it is definitely possible. I don’t use block code for anything though, I simply did it to prove a point. as @Seb said, this would be a great opportunity to learn python or C++.

Having a decent knowledge of both languages, and having used both languages for applications in robotics, and applications out of robotics, I can tell you with confidence that Python is easier to learn, and for simple robot programs (a PID could fit in this) Python is great. However, if you know you will be writing a lot of code… I would not use Python since working with multiple source files in V5 & python is a pain. (possible, but a pain)

I think I would go insane if I had to fit this in one source file… (or have to constantly modify code on an SD card)
