Arduino Programs Blink
This sketch demonstrates the Keyboard library.
For Leonardo and Due boards only.
When you connect pin 2 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, Micro, Due, LilyPad USB, or Yún
- wire to connect D2 to ground
