SparkFun Joystick Shield Kit

The SparkFun Joystick Shield Kit contains all the parts you need to enable your Arduino with a joystick. The shield sits on top of your Arduino and turns it into a simple controller. Five momentary push buttons and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers. Soldering is required, but it’s relatively easy and requires minimal tools. We even have a step by step guide.

The momentary push buttons are connected to Arduino digital pins 2-6; when pressed they will pull the pin low. Vertical movement of the joystick will produce a proportional analog voltage on analog pin 0, likewise, horizontal movement of the joystick can be tracked on analog pin 1.
