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
