This controller is a cheap knockoff of the Nintendo Wii Nunchuck controller. It has a two-axis joystick, two pushbuttons ("Z" and "C"), and an internal three-axis accelerometer. Plugs into the bottom of your Wiimote, or plugs into the P1/P2 ports on the Video Game Shield. To be clear, this is a cheap knockoff, not an official Nintendo product, but it works great with the Video Game Shield.
