connection port also has a larger size. The Nunchuk can be connected to any microcontroller capable of I²C (e.g., Arduino's Atmel AVR), where the accelerometer, joystick and buttons data may be accessed. Todbot has created the Wiichuk, an adapter to facilitate connecting the Nunchuk to an Arduino board. In 2008, wireless Nunchuks became available from third party providers, not requiring the cord that links the Wii Remote with the Nunchuk. The Nunchuk is generally available in white and black. Sky blue Nunchuks were available in Japan as a prize for a contest used to promote Wii Sports Resort. Red Nunchuks are bundled with the red Mario anniversary Wii console and Wii Mini. Blue Nunchuks are bundled with the European blue Wii Family Edition consoles with the inclusion of Mario & Sonic at the London 2012 Olympic Games released on November 18, 2011. A gold Nunchuk was offered to Nintendo Club members for a limited time to complement Skyward Swords gold Wii Remote Plus. Classic Controller There are two versions of the Classic Controller, the original Classic Controller and the Classic Controller Pro. At the 2006 Electronic Entertainment Expo Nintendo introduced the Classic Controller, which plugs into the Wii Remote via a cord in a similar fashion to the Nunchuk. Unlike most accessories, the Classic Controller largely usurps the Remote's functionality, with the Remote's buttons duplicated on the Controller. The Remote is used primarily as a wireless transmitter for the Controller and where applicable retains its pointing-device functionality. It can also still be used as a valid, active controller by another player in multiplayer modes of games like Bust-A-Move Bash! and SpeedZone. The Classic Controller is reminiscent of the Super NES controller, being the same size and having the , , , and buttons and directional pad in the same location. It also contains two analog sticks and two extra shoulder buttons used to replicate additional components found on the Nintendo GameCube controller. The controller is primarily used for Virtual Console titles, with several titles requiring either the Classic or GameCube controller to play, being optimized for the Classic Controller. Dozens of Wii titles are also compatible with the controller to allow for a more traditional control scheme. Wii MotionPlus The Wii MotionPlus is an expansion device that allows the Wii Remote to more accurately capture complex motion. Incorporated with a custom version of the Wii Remote Jacket, the Wii MotionPlus
