# So you would like to read the source code? Nice!
# Just be warned, this application uses Thread and a UI Toolkit called 
# Kivy to run. If you are unsure of what functions do, consider 
# checking out the kivy docs at https://kivy.org/doc. 
# It also uses the pyserial library for communication with the micro-
# controller with RS232
