Help Needed for Dust Collection Blast Gates Arduino Code Bug


I haired a professional several months ago to write an Arduino code to automate my dust collection blast gates. It was functioning without problems during the first tests and light use, but after using the system for longer time I faced a code bug that I cannot solve, so I created a new repository “for the 1st time” HERE with an issue as suggested in THIS TOPIC, but I couldn’t find the proper way to use the tools and options in that page to invite people for help.

I appreciate your help, and please feel free to contribute and ask any question.

Thank you.


Any suggestions please?
