Joystick is very alike to the ‘analog’ joysticks on PS2 controllers.
This is a joystick very alike to the ‘analog’ joysticks on PS2 controllers. It is a self-centering spring loaded joystick, meaning when you release the joystick it will center itself. It also contains a comfortable cup-type cap which gives the feel of a thumb-stick.
The goal of the joystick is to communicate motion in 2D (2-axis). This is achieved by outside two independent 10K potentiometers (one per axis). These potentiometers are used as dual adjustable voltage dividers, providing 2-Axis analog input in a control stick form.
