The Wii Remote, also known as "Wiimote" is the primary controller for the Wii's console. A differentiating feature of the Wii Remote is its motion sensing capability. The combination of built-in accelerometers and infrared detection helps it to sense its position in 3D space when pointed at the LEDs within the Sensor Bar. As a result the user can control the game using physical gestures supported by traditional button pressing. This makes the experience interesting and convenient. The controller is connected to the console using Bluetooth. The Nunchuk comes with the Wii retail package featuring accelerometer and a traditional analog stick and two trigger buttons. An attachable wrist strap is also provided to prevent the unintentional dropping or throwing the Wii Remote. The remote along with being a powerful device is also delicate therefore a Wii Remote Jacket is also provided for protection. The Wii MotionPlus and the Wii Vitality Sensor are utility devices that connect through the Wii Remote.

Announced at the Tokyo Game Show in 2005, the Wii remote has become a popular device due to the functions it performs and contrast it exhibits relative to other gaming controllers.

The Wii console has 512 megabytes of internal flash memory. An additional SD card slot is also available for external storage. An SD card functions as a storage device for uploading photos and creating backup of game data. Also, downloaded Virtual Console and WiiWare games can be saved on the SD card. This option offers an alternative to the console's limited memory storage. Traditionally such a device is referred to as the "memory card." "SD" is a type of memory card. The SD card also provides the facility of creating customized in-game music which can be stored in MP3 format on the SD card itself. This feature was first shown in Excite Truck. An update of the SD card, the SDHC card has increased the limit on SD card size from 2 GB to 32 GB.

The Wii remote and the Memory Storage capability play an important role in completing the Nintendo Wii. Although the popularity of the Wii remote is much more than the console's memory storage capability, the Wii cannot do what it does without its memory feature. In general all the components of the Wii are dependent and are integral for making the console work.
