Arduino mouse moving

I want to make a program that moves the mouse (cursor) for me. I don't really care much for implementing input from anything, i just wanna make a program that moves it on its own.

for example: Maybe a program that'll move the mouse in circles over and over

I'm using an arduino uno (im kinda new to arduino)

You need an Arduino that can do that.

That's not one of them.

A Micro or Leonardo can, as can the Teensys.

thanks for the information : >

many option: 1-a simple motor and a holder that either move the mouse or something near the sensor (beneat)

2-open up a mecanical mouse and attach stepper motor or unlimited servo to both the vertical and horizontal optical rotary encoder.

3-decode the signal emited by a PS2 or USB mouse and send you own data without any mouse

4-plenty of software online that can do the same directly on the PC without having to joggle with a mouse, but you need to download and run them.

i guess for a pratical joke, you could fit a minuature arduino inside a mouse and intercept the optical sensor before resending the data. you'll need a scope and i dont know if a arduino could do it fast enought without lag.

@pomelum, refer to reply #1. There are Arduinos that can appear like a mouse to the PC USB port.
