# Phantom Mouse Jiggler
## Overview
https://youtu.be/hdfkuC3CgSQ
Ever had your cursor move a little bit while you weren't even touching the mouse? Freaky! This MakeCode program will turn your Gemma M0 into a Phantom Mouse Jiggler. When plugged in to a computer, it will wait patiently, and then occasionally take over the mouse cursor from the user and move it around back and forth. Maddening!
Danger:
One very powerful feature of the Gemma M0 (and other ATSAMD21 ARM Cortex M0-based microcontrollers) is its ability to appear as a keyboard or mouse when plugged into a computer’s USB port.
The Gemma M0 can pretend to be a USB mouse, so we'll take a look at how to program it with MakeCode to wait dormant for long periods of time, and then jiggle the cursor for a few seconds!

## Parts
All you'll need is a Gemma M0 and a short USB cable to program and then deploy this prank!
