Simple USB mouse jiggler using a Digispark ATtiny85 USB development board.
The board is flashed once using Arduino IDE on Windows. After that, it appears to the computer as a standard USB HID mouse and moves the pointer slightly at a fixed interval.
Responsible use only: Use this only on computers you own or are explicitly authorized to manage. Do not use it to bypass workplace screen-locks, monitoring, endpoint controls, or security policy.
