Analog joysticks are a great way to add some control in your projects. The module has 5 pins: Vcc, Ground, X, Y, Key. The thumbstick is analog and should provide more accurate readings than simple ‘directional’ joysticks tat use some forms of buttons, or mechanical switches. Additionally, you can press the joystick down to activate a ‘press to select’ push-button.
