+\section{Przerobienie skryptu Python} 
+Postanowiłem przerobić pythonowy skrypt na taki który imituje sensor temperatury  \\
+Chciałem stworzyć skrypt który z jednej strony jest prosty do napisania, a z drugiej imituje faktyczną praktyczną funkcjonalność którą można by użyć na przykład przy urządzeniach internetu rzeczy \\
