Sparkfun SPARK09760 Arduino Joystick Shield Kit

The Joystick Shield kit contains all the parts needed to enable an Arduino with a joystick. The shield sits on top of the Arduino and turns it into a simple controller. Five momentary push buttons (4+ joystick select button) and a two-axis thumb joystick gives the Arduino functionality on the level of old Nintendo controllers. Soldering is required, but it's relatively easy and requires minimal tools and there is an step by step guide.

The momentary push buttons are connected to Arduino digital pins 2-6; when pressed they will pull the pin low (utilizing the internal pull-ups of the Arduino). 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.

• The kit contains the following items:
• 1x Joystick Shield PCB
• 4x Momentary Push Button Switch - 12mm Square
• 1x Thumb Joystick
• 1x Mini Push Button Switch (breaks out Arduino's reset switch)
• 2x 6-pin Arduino Stackable Header
• 2x 8-pin Arduino Stackable Header
