It reminds me of Elevator Saga.

Reminds me of when I had to build a mock 4-floor elevator in school, using old printer parts and a PLC, programmed using Ladder. Python would have been so much nicer…
I hate programming in ladder, but it does make online debugging a breeze.
Yeah, that’s true, being able to just see what’s going on in all parts of the program at all times was rather useful.
