| 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 | |
