What is the best programming language to modify a manually operated machine?

Question

The best way to program machines e.g a lathe Machine, milling machine, fatigue machine that are manually operated but can be programmed to reduce the manual work by just inputting the desired data

Answer 1

I assume you are using micro controllers to automate stuff so the best language is Embedded C or C99 or C++.

You could also use assembly languages but they are a painful to learn and not worth the time.

You could also use python/c/c++ with raspberry pi for automation.
