O. CPU Temperature

One of the most important and critical aspects of an overclocked raspberry pi is the temperature, and even though it will start throttling thus not causing any damages to hardware (melted cpu), it is still something you need to look out for and prevent. Throttling implies lower performances and we definitely don't want that.

I did not want to install any additional python packages (gpiozero) or even lm-sensors , I wanted to make something from scratch.
