6
7  For Leonardo and Due boards only.
8
9  When you connect pin 2 to ground, it creates a new window with a key
10
11  combination (CTRL-N), then types in the Blink sketch, then auto-formats the
12
13  text using another key combination (CTRL-T), then uploads the sketch to the
14
15  currently selected Arduino using a final key combination (CTRL-U).

19  - Arduino Leonardo, Micro, Due, LilyPad USB, or Yún
20
21  - wire to connect D2 to ground
