Aduino Based Video Game Controller

Instruction video : 

Make an Arduino based game controller

Arduino Script:

// Monkey Game controller - By Jee Van Kur is not a Monkey ;)

const int button[] = {10, 11, 12}; // pins
int i = 0;

void setup() {
  Serial.begin(9600);
  while(i<3)                      // define pins
  {
    pinMode(button[i], INPUT);
    digitalWrite(button[i], HIGH);
    i++; 
  }
}

void loop(){
  int sum = 0;
  for(i=0;i<3;i++)

  {
    if(digitalRead(button[i]) == LOW)
    sum += (i+1)*pow(2, i);               // sum up the pressed button indexes
  }
  Serial.println(sum);        // print value
  delay(50);
}

// I am of no use without processing

Make your own game controllers and have fun. Also post a pic in the comments if you make one.. would love to see it..
