Wouldn’t it be awesome if you could use a Wii MotionPlus controller to control your Arduino projects? We are going to learn how to program your Arduino to communicate with the Wii controller’s i2c (inter-integrated circuits) protocol, so that you can gather data from the gyroscope in the Wii controler. To get started hacking into the Wii controller, all you will need is a few resistors and jumper wires! Once you have the hack working there is any number of ways you can use it. For example you could make three motion controlled servos using the data from the Wii controller! To get started learning how to get your Arduino to talk to your Wii controller check out the following instructions from rileyporter.
