Making a half-convincing USB Mouse Jiggler on the cheap

I object to USB Mouse Jigglers being £20-£30 on Amazon for something a microcontroller should be able to do with ease, in an unconfigurable/unknown state when it comes to how they describe themselves to the host machine.

We can do better, with a reprogrammable version for about £6.

There are existing guides to each part of this, and I've linked them inline. Here's a great one for people less familiar with Arduino, but this guide assumes basic knowledge of Arduino.
