Keyboard logout
|
||
|
|
|
||
|
|
This sketch demonstrates the Keyboard library.
|
||
|
|
|
||
|
|
When you connect pin 2 to ground, it performs a logout.
|
||
|
|
It uses keyboard combinations to do this, as follows:
|
||
|
|
|
||
|
|
On Windows, CTRL-ALT-DEL followed by ALT-l
|
||
|
|
On Ubuntu, CTRL-ALT-DEL, and ENTER
|
||
|
|
On OSX, CMD-SHIFT-q
|
||
|
|
|
||
|
|
To wake: Spacebar.
|
||
|
|
|
||
|
|
Circuit:
|
||
|
|
- Arduino Leonardo or Micro
|
||
|
|
- wire to connect D2 to ground
