Library to set any arduino as a USB mouse.
Move mouse pointer by calling method: UsbMouse.move(x,y,z) where z indicates the wheel.
Set buttons (left,right,middle) by calling method: UsbMouse.set_buttons(l,r,m).
Copy directory under your arduino libraries directory.
In arduino, go to examples -> UsbMouse -> UsbMouseDemo1
