The first problem that I found was how to connect the control without an adapter, I was planning to make one, but
when I was searching for the nunchuck I also found the Wii motion plus accesory then I did notice that it haves a
Male interface it haves holes to put wires, I did a search for Wii motion hacks with arduino and I found some code.
Second problem I found was that the code to hack both nunchuck and wii motion plus are outdated and you have
to change some commands, like Serial.begin, Wire.write instead of Wire.send etc,
So I had to fix the code and also I added leds!
Step 1: Materials
1 Wii motion Plus
1 Wii Nunchuck
6 Resistors 220 ohm
6 Leds (any color)
Solid core jumper wires
Step 2: Build it

From the Wiimote side
Pin Cable color Description
1 Green SDA. I²C Serial Data
2 Orange Ground
3 - Not connected.
4 - Not connected.
5 Red 3.3V
6 Yellow SCL. I²C Serial Clock. (400 kHz)
Get 4 cables, and put them in the correct place, in the photo the orange wire is ground, is very important to notice
that the powerline uses 3.3V, dont use the 5V powerline it will not fry your control, but is better to play Safe.
Connect Pin 5 Green cable to Analog 4(A4) and Pin 2 Yellow cable to Analog 5(A5) to the arduino, Pin 1 Red cable to Power 3.3V
and Pin 6 (in the photo the cable is orange) to ground.
