Salutations I am a student at Northern Arizona University,

      I am currently a participating in a robotics competition. I have a degree in Mechanical engineering and I am currently pursuing a second degree in computer science. The robot we are making for the competition is a soccer playing robot this is my first time doing programing like this. I have an understanding in Python and Java. We are using a Raspberry Pi 3 for the brains of the robot. I have installed Raspian and Retropie on-top to facilitate in creating a way to communicate wireless through Bluetooth. I am confused on how to create a program to create methods to layer onto the button events.


     Can someone help with documentation I have been searching the web and I have not been successful in acquiring information on the subject at hand. I need an angel, who is out there that can help.
