General LabVIEW questions from a VERY new user

[ctccromer]

That's very helpful, thanks! I'm trying to copy that into my periodic tasks but I don't recognize a few of those VI's. What is the array looking thing on the left? and the Start and Mechanism Op VI's? Also, I put it inside a While loop, but I don't see the slot at the top where "Go" is in your picture either
Thank you very much for the help

EDIT: i compiled a video of our progress so far. Everything coded in the video has been done with your help here and I just want to thank you very much! Here's the video if you'd like to see
