In a project of mine I use temperature sensors and an Arduino to dimm a light bulb to keep a box warm (in a certain temperature range above room temperature). I want others to look at my code if it has enough/the right safety measures so the box doesn't overheat which is what I want to prevent in case the temperature sensors or other parts of the hardware are faulty (or if my code itself has a bug I don't know of).
Of course I would provide the complete code and a rough overview over the hardware but I asked myself if the Code Review SE or the Arduino SE is the right site for this question.
