MOUSE JIGGLER pretending to be a computer mouse

janchar 2877 31

TL;DR

A Raspberry Pi Zero (RP2040) Arduino mouse jiggler emulates a USB computer mouse to keep Windows from entering standby during inactivity.
It moves the pointer 5 pixels to the right every 1 minute, then moves it back 5 pixels, avoiding the erratic cursor behavior of commercial jigglers.
A soldered button between pin 1 and pin 3 toggles activation, while the RGB LED shows operating status.
Uploading is done in Windows 10 by holding BOOT, opening the USB folder, and copying RP2040_simulation_motion_mouse.ino.uf2.

Something feels that if this continues, I could use something like this at work. With the new changes, screens go blank after a few seconds of inactivity ;/

In fact, probably the easiest solution without installing anything is to run e.g. Notepad, and put something heavy enough on the spacebar key to keep it pressed all the time
