/*
  Arduino Programs Blink
 
 This sketch demonstrates the Keyboard library.
 
 When you connect pin 12 to ground, it creates a new
 window with a key combination (CTRL-N),
 then types in the Blink sketch, then auto-formats the text
 using another key combination (CTRL-T), then 
 uploads the sketch to the currently selected Arduino using 
 a final key combination (CTRL-U).
 
 Circuit:
 * Arduino Leonardo
 * wire to connect D12 to ground.
