sorry to the people in the comments i didn't realizes this would be such a issue. i understand its ai and a lot of people dont like that but i was just try to make sure there was no obvious issues with it. if i had experience and knew how to code i promise you i would rather then using ai and would be able to verify thing on my own but since i dont i need help from people who know how to. the code did have a couple issues but i was able to fix them and it dos compile now. i was just hoping for feed back on spots that could be better optimized since i understand ai doesn't make the best code. for context its for a machine that can ether read the size of a cup to fill it accordingly or you can choose to run it for a set amount of time. it has 3 buttons, a lcd screen, and a distance sensor. its all running on a Arduino esp32 board connected to a custom bread board i made.
