Serial data from arduino to processing does not update

Projects Programming

All pins are first set to INPUT_PULLUP in setup then in loop() I check wether they touch with the first for loop, second loop is to reset the data sent to processing.

  for (int i = 0; i < 12; i++) {
    pinMode(i, OUTPUT);
    digitalWrite(i, LOW);
    for (int x = 0; x < 12; x++) {
      if (i != x) {
        if (digitalRead(x) == LOW) {
          partsConnected[x] = 1;
        }
      }
    }
    pinMode(i, INPUT_PULLUP);
  }
  sendArrayData();
  for (int i = 0; i < 12; i++) {
    partsConnected[i] = 0;
  }
