GameCube Controller + Arduino (My First Project)

Projects General Guidance
1

HI! I'm new here and new to arduino and circuits overall. My first project is to interface the arduino with a gamecube controller.

I have found gamecube pinouts on google and have striped the gamecube controller wires. Then I soldered them to jumpers so I can connect everything easier. My current problem is that the arduino returns only 0's.

Current Pinout:
Yellow 5V power supply (used by rumble motor).
Red DATA line: bi-directional data to/from console, pull-up to 3.43V
Green & White Ground.
Blue 1 3.3V logic supply

The red cable is connected to the digital pin 2 on the arduino.

This is my current code:

const int dataPin =  2; 

void setup() {
  // put your setup code here, to run once:
pinMode(dataPin, INPUT);
Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly: 
  int sensorValue = digitalRead(dataPin);
  Serial.println(sensorValue);
}

As I said, I only see 0's in the serial monitor. Any help is appreciated. Thank you!

Did you provide a pull-up? The article I found says they used a 1K pull up to 3.43V. Will probably work with 3.3V.

The interface seems to require microsecond timing so you may need to set up a timer interrupt to send out command data and clock in received data.

Ok how do I wire in a pull-up?

Also any idea on the coding required to interrupt the signal?

This is my first project and I mostly program in java not C, so I'm working on learning the syntax.

I'm thinking about trying to work on something similar but theres a small snag. I bought a small arduino micro clone and I haven't had a chance to play around with it yet but it says the 3.3V regulator doesn't work when not powered by USB, which it won't be. If I regulate my own 3.3V off board can I just connect it to the Arduino 3.3V pin can I just treat it like a normal Arduino setup or is there something wrong with bypassing the Arduino's 3.3V regulator and attaching your own?
