This 5 Channel Way Tactile Switch Breakout Board is basically the world's smallest joystick.
This 5-way tactile switch (up, down, left, right, and center click) allows for joystick-like control in a very small package. This breadboard-friendly board breaks out all the switch signals, and includes pullup resistors configured so that the outputs read low when pressed, and high otherwise. (If you wish, you can reverse the power leads for pull-down operation.)
