In this Instructable I am going to show you how to connect the Nunchuk to the Arduino via the WiiChuck adapter. There are a couple of steps to this, first, we will hook it up, then we'll download the library and then download the code.
1 WiiChuck Adapter
4 Jumper Wires
1 Arduino Board (with USB Cable)
Step 1: Plugging in the WiiChuck
GND to GND (obviuosly
+ to +5V
C to Analog Input pin 5
D to Analog Input pin 4
Then plug in the board with the labels facing the groove on the nunckuck, as shown in the picture.
I soldered the wires going away from the labels, so just make it so the wires are point in the same direction as the groove.
