/*Overall, the code orchestrates a control cycle for a refrigeration system,
incorporating temperature monitoring, cooling, defrosting, and various indicators for system status.
The LCD provides real-time information, and the code includes mechanisms to handle potential issues like 
cooling failures.
Further analytic explanation can be found in the doc file within the same folder*/
