Moving the Qwiic joystick will move your mouse on the screen. Pressing down on the button will cause a left
mouse click. Once you stop pressing down on the joystick, it will release the left mouse click. Depending on the
orientation for the vertical, you can invert the mouse's movement using the
invertMouse
variable at the beginning
of the example code.
