This is an alternative firmware for USBasp that provides mouse jiggling functionality instead of programming AVR and compatibles.
After connecting to USB, it moves your mouse cursor along the circular path. You can change motion speed by setting the clock speed jumper.
I had a bunch of USBasps lying around my home, so I thought I would reuse one of them as a device for professional remote workers :)
Other than that, I just wanted to play around with USB and electronics during a weekend. I have no plans for further development.
