A few HID attacks with the DigiSpark board. In addition, my scripts use the DigiKeyPlus library, a custom DigiKeyboard wrapper I wrote. The library automates certain tasks (such as opening the run/spotlight menus and turning up volume) while also adding more keys (like volume or the other arrow keys) to the library. A few commands are also simplified (println and sendKeyStroke have been combined into Type).
Although I'm still working on documentation for DigiKeyPlus, all of the scripts I've written here do work and should be pretty straightforward to read (I also added comments to them).
My scripts also use a button to launch the attack, attached to Pin 0. If you don't want to use a button, change the number from 0 to -1 in the scripts (it makes sense when you read the comments). If you don't use a button, the attack simply runs on each loop() call, with a 5 second delay between runs.
