Hi, I am a student building a pinball machine powered by arduino. I have been having trouble with the code that I have put in below with getting my pushbuttons to add a specific amount to the 8 digit display. If anyone knows how to get the buttons to work and increase the numbers on the display or if you see something wrong in the code that is causing me my problems please let me know.
