/* Pin definitions. Use whatever pins suit your project, but
   be mindful that the 'CLK' buttons need to be connected to a
   pin with a hardware interrupt. This may vary depending
   on the exact board model. I'm using a Leonardo 
   
WARNING!!! If you want to change pin assignments, you will also have to edit the 
GETJSBIT handlers, as the pin assignments (port registers) are hardcoded there!
